A t-shirt-stuffed Linux store has opened for business, the proceeds from which support the Linux Foundation. But since Linux users are such penny-pinchers, $18 is probably more than they’ll pay for a single garment of clothing. [LinuxStore via CrunchGear]
First law of gadget recessionomics: Take something you make, which is great, make it ever so less great, and sell it for ever so less money. That’s how you end up with products like Microsoft’s SideWinder ʹ keyboard.
$60 MSRP, $46 retail.
The SideWinder X6 was a marvelous fresh start for Microsoft’s rejuvenated gaming hardware division, designed with a brooding Death Star aesthetic, shit hot jog wheels, and a hot-swappable detachable keyboard that can be hooked up to the left or right side. It’s just $20 pricier MSRP (but retail, $12) than the Ͷ, and I’ll tell you straight up, a better deal.
The SideWinder X4 is virtually identical at the core—same basic keyboard layout (including the too-long spacebar), chaos-red backlighting, and laptop-esque throw distance for the keys—but it ditches the most lovable aspects of the X6: the jog wheels and the detachable keyboard. Instead, it touts anti-ghosting, so you can mash 26 keys at once and have them all register. Also, it’s got fewer macros total (though really, it still has plenty enough). And a smaller wrist rest.
The core features are solid. It held up to the Twister-style keyboard gymnastics you occasionally have to perform in Battlefield: Bad Company 2, and the snap of the keys is on point: Crisp and squishy, like a croissant.
But! The fact remains, its older, more capable brother costs a few nickels more and is well worth the extra scratch. So if you can find the X4 for $20 in a bargain bin in a couple months and need a basic gaming, then it’d be a solid buy. In the meantime, if your′e gonna get a gaming keyboard, step up to the X6. (Personally, I’m waiting for the inevitable X10.)
We’re still suckers for the whole brimstone and fire in space aesthetic (for now)
A solid “basics” gaming keyboard, but why go for basics when it comes to gaming gear?
Software for keyboard is kinda eh compared to Logitech, SteelSeries and Razer
Too many features stripped for such a small price reduction
Google added bike lanes and bicycle directions to Google Maps today, allowing you to find routes that aren’t too hilly or congested. It’s pretty awesome!
Bike functionality is available for over 150 American cities at the moment, but it’s safe to assume that, like everything Google does, it will eventually expand to cover most of the planet. [Google Maps via Physorg]
It’s confirmed: Space is bubbling with the potential for life. The Heterodyne Instrument for the Far Infrared—on board the Herschel Space Observatory—has sent a high resolution analysis of the Orion Nebula’s chemistry. It has scientists very excited.
It is astonishing to see how well HIFI works. We obtained this spectrum in a few hours and it already beats any other spectrum, at any other wavelength, ever taken of Orion. Organics are everywhere in this spectrum, even at the lowest levels, which hints at the fidelity of HIFI. The development of HIFI took eight years but it was really worth waiting for.
That’s Frank Helmich, HIFI principal investigator of SRON Netherlands Institute for Space Research, getting his pants wet over his new toy. The Orion spectrum—capture back in January—contains all the molecules needed for the creation of life, “water, carbon monoxide, formaldehyde, methanol, dimethyl ether, hydrogen cyanide, sulphur oxide, sulphur dioxide and their isotope analogues.”
I just hope those molecules are just not sitting around, twiddling around, without actually recombining to create five-eyed aliens with purple tentacles. [ESA via Wired]
This daily calendar mixes analog, digital, nature, and poetry all in one: Every autumn day, each of its pages will fall off automatically, torn by a clever mechanism at its top. As this video shows, it works great. But why?
Because in autumn, leaf falls, that’s why. And because it was commissioned as a promotional tool for clients by leaf blower manufacturer Stihl. [Direct Daily]
With stories abounding of identity theft aided by information lifted from discarded storage devices, you want devices you no longer plan to use to have no usable information when they head out the door. Here’s how to wipe them clean.
Sure, you could erase the contents of the drive, but keep this in mind: the act of erasing a file does not remove it from a storage device.
When you erase/delete a file from your computer, it’s not really gone until the areas of the disk it used are overwritten by new information. If you use the normal Windows delete function, the “deleted” file is sent to the Recycle Bin until the space it uses is required by other files. If you use Shift-Delete to bypass the Recycle Bin, the space occupied by the file is marked as available for other files. However, the file could be recovered days or even weeks later with third-party data recovery software. As long as the operating system does not reuse the space occupied by a file with another file, the “deleted” file can be recovered.
With SSDs, the erased file situation is even more complex. SSDs store data in blocks rather than in sectors as with magnetic storage. Overwriting a block was previously used involves copying the contents of the block to cache, wiping the block’s contents, delete the block to be overwritten from cache, writing the new data to cache, and rewriting the block with the new data. As an SSD is used with files that are deleted or changed frequently, the performance can drop unless the drive (and operating system) support a technology called TRIM that wipes out deleted data blocks as soon as the file using the blocks is deleted. TRIM is supported by Windows 7 and by some late model SSDs, but not by older Windows versions. So, disk wiping can be both a security feature and a performance improvement strategy.
While erasing files simply marks file space as available for reuse, data wiping overwrites all data space on a storage device, replacing useful data with garbage data. Depending upon the method used, the overwrite data could be zeros (also known as “zero-fill”) or could be various random patterns.
Products that can be used for wiping hard disks might not be suitable for wiping other types of drives. In this article, we will look at methods for securely wiping hard disks, USB flash memory devices, flash memory cards, and SSDs.
Time Needed: several hours (varies with size and speed of drive)
Software: Hard disk utility software from your drive vendor
Media: blank CD or floppy disk
Although writing zeroes across the entire hard disk surface (aka “zero-filling”) is not sufficient to meet government data sanitation (disk wiping) standards such as DoD 5220.22-M or the more comprehensive Standards and Technologies (NIST) Special Publication 800-88, overwriting the entire hard disk prevents most types of data recovery from being successful.
Here’s where to get zero-fill software from hard disk vendors:
Hitachi
Drive Fitness Test (see website for specific models supported)
http://www.hitachigst.com/hdd/support/download.htm#DFT
Select the Erase Drive feature to zero-fill your hard disk
Samsung
HUtil (see website for specific models supported)
http://www.samsung.com/global/business/hdd/support/utilities/Support_HUTIL.html
Use Tool, Erase HDD to zero-fill your hard disk
Seagate (including Maxtor)
SeaTools for DOS (see website for specific models supported)
http://www.seagate.com/www/en-us/support/downloads/seatools
Use Full Erase to zero-fill your hard disk
Western Digital
Data Lifeguard Diagnostics (select drive model for specific version recommended)
http://support.wdc.com/product/download.asp?lang=en
Use Write Zeros to drive to zero-fill your hard disk
1. Determine the brand and model of hard disk you want to overwrite.
2. Download a CD ISO image or a floppy disk image (depending upon your equipment) and use the image to create bootable media. The floppy disk image is self-contained: run it, insert a blank floppy disk when prompted, and the image is created on the disk. You will need to use a CD burning program that works with ISO images to convert the ISO image into a bootable CD.
3. Restart your computer with the bootable media you created in Step 2.
4. Select the hard disk to zero-fill when prompted.
5. Choose the option to zero-fill the hard disk.
6. When the program is finished, follow the on-screen instructions to shut down or restart your computer.
7. Remove the wiped hard disk; you can now reuse or recycle the hard disk.
Secure wiping goes beyond zero-fill operations, and provides an extra level of security. Most secure wiping programs are designed to meet DoD 5220 standards, which require three passes of overwriting with a special numeric pattern and verification. More information about this and other secure standards are available from the DataErasure website.
(Note that the 2007 revision of the Defense Security Service, Updated DSS Clearing and Sanitization Matrix (June 28, 2007) (PDF) now recommends degaussing or drive destruction for maximum protection.
Stanford University’s Disk and Data Sanitization Policy and Guidelines, a must-read for understanding data wiping issues, recommends Darik’s Boot and Nuke (DBAN) for secure hard disk wiping.
Time Needed: several hours (varies with size and speed of drive)
Software: Darik’s Boot and Nuke (DBAN); available from http://www.dban.org/
Media: blank CD (all versions) or floppy disk (version 1.0.7 and older versions)
1. Download the DBAN boot image ZIP file (we used version 1.0.7 and beta version 2.0 for this article); we downloaded the ISO image for CD burning, but a floppy disk builder is also available
2. Extract the contents of the compressed file.
3. Burn the ISO image file extracted in Step 2 to CD; see our article on how to do this, or use the built-in ISO CD image burning support in Windows 7. If you downloaded the floppy image builder, run the program to create a bootable floppy disk.
4. Restart the computer using the CD or floppy disk created in Step 3.
5. Press Enter to run DBAN in interactive mode.
6. Use up and down arrow keys to highlight the drive to wipe.
7. Press the space bar to select the drive.
8. Press M to select the wiping method.
9. Press F10 to begin the wipe process.
10. At the end of the process, shut down the system. You can reuse or recycle the wiped hard disk.
Note: if DBAN is unable to recognize your SATA hard disks, configure your system BIOS to use IDE mode rather than AHCI mode.
Programs such as DBAN or vendor-supplied hard disk utilities are limited in the devices they support: they are designed to work with internal ATA/IDE or SATA hard disks only. Programs that work with flash memory cards and USB flash drives often support hard disks as well, enabling you to use a single program for all disk wiping processes. Roadkil’s DataWipe can be used with any hard disk, floppy disk, or flash drive that has a drive letter.
Time Needed: Varies; from a few minutes to several hours, depending upon size and speed of drive and computer
Software: Roadkil’s DiskWipe, available from http://www.roadkil.net/
Media: Can be run from Windows desktop
1. Download Roadkil’s DiskWipe.
2. Extract the contents of the compressed file.
3. Open DiskWipe. If you are running Windows Vista or Windows 7, right-click the program icon and select Run as Administrator.
4. Select the drive to wipe.
5. Select the type of wipe to perform; DiskWipe can zero-fill the disk or write random data.
6. Enter the number of passes.
7. Click Erase to start the process.
8. At the end of the process, close the program. You can reuse the wiped disk.
To solve write performance problems on drives that don’t support TRIM (check with your drive vendor for firmware upgrades) is to use wiper.exe (included with some SSDs) or to run the Secure Erase feature supported in most recent ATA/IDE and SATA drives. The Secure Erase feature can be activated on many systems by running Secure Erase 4.0 (HDDerase.exe), available from http://cmrr.ucsd.edu/people/Hughes/SecureErase.shtml. Version 4.0 works with most recent ATA/IDE and SATA hard disks and SSDs, but if you use an Intel X-25M, X-25E, or X-18M SSD, follow this link to download Secure Erase 3.3 http://www.iishacks.com/index.php/2009/06/30/how-to-secure-erase-reset-an-intel-solid-state-drive-ssd/. Note that it is no longer being developed, and we were unable to use it on a system running an AMD 690 chipset.
SDelete is a free program from Microsoft’s TechNet Sysinternals collection. It runs from the command line, and can be used to wipe drives, wipe files, or wipe free space.
Time Needed: Varies; from a few minutes to several hours, depending upon size and speed of drive and computer
Software: TechNet Sysinternal’s SDelete, available from http://technet.microsoft.com
Media: Can be run from Windows desktop
1. Download SDelete.
2. Extract the contents of the compressed file.
3. Copy sdelete.exe to c:windowssystem32 (this will enable you to run it from any location)
4. Open a command prompt session with Administrator rights.
5. To wipe all files on drive X: and its subdirectories and to wipe free space, enter Sdelete -p 2 –s -z X:*.* (to see all command-line switches, enter Sdelete with no options)
6. Wait; the program displays status messages as it runs. When the program is finished, you can reuse or dispose of the drive.
We used demo versions of two popular data recovery programs to evaluate some of the disk wiping programs discussed in this article. To determine whether a typical data recovery program could recover files on a SD card wipe with Roadkil’s DiskWipe, we first of all formatted the card using a card reader. Ontrack’s EasyRecovery Data Recovery (available from http://www.ontrack.com) had no difficulty finding folders and files to retrieve.
However, when we used DiskWipe to wipe the drive using a one-pass blank disk (zero fill) operation, EasyRecovery DataRecovery was unable to find the file system, let alone any files or folders.
After reformatting the card, taking a few photos, and deleting the photos, EasyRecovery Data Recovery was able to find the new photos, but the contents of the card before running WipeDisk were unrecoverable.
To evaluate SDelete, we used SDelete to wipe all of the files on a hard disk, but omitted the –z switch; when –z is not used, SDelete deletes files and renames them, but does not clear free space. To determine what might be visible, we used a demo version of Disk Doctors NTFS Data Recovery software, available from http://www.diskdoctors.net.
Disk Doctors were able to locate the deleted folder and Outlook Express message folders, but SDelete had renamed them from their original names and DBX extensions (Outlook Express message folders). If you use SDelete, it’s very important that you take time to use the –z switch to clear free space on the disk (once a file is deleted, the space it occupies is free space).
We also used Disk Doctors to evaluate the effectiveness of a freeware program called Eraser, which can delete and overwrite files and folders from the right-click menu. We created a documents folder with a subfolder called Figures and used Eraser to overwrite the folder and subfolder using its default settings.
Disk Doctors was able to locate the folders, but the contents are files with garbage names and are zero bytes in size – except for leftover word processing temporary files (files that begin with $). These filenames were not changed, which could enable a snooper to figure out the names of the files in the folder – although the files themselves were destroyed. By using more overwrites or different methods available with Eraser, a more thorough wiping may be possible.
We’ve highlighted a variety of free ways to protect data on castoff drives from being retrieved. As you can see, your best bet is to overwrite data directly, but you also might want to consider using a program such as SDelete to scramble filenames first and then use a disk wiper such as Eraser or WipeDisk to finish the job.
Use demo versions of data recovery programs such as Ontrack Easy Recovery Data Recovery, Disk Doctors Data Recovery (various editions for NTFS, FAT, and flash media), and others to evaluate the effectiveness of your data wiping procedures. Remember, the full versions of these and other data recovery programs can save your data if you accidentally format or partition a disk because, until the data is overwritten, it’s still there.

Apart from the name—which I personally approve of very much—Zenitum’s iKat app has another cool edge to it. It’s (we think) the first augmented reality phone app to work without a marker, or real-world prompt.
The app itself is pretty basic, just a cartoon-like pet running around on whatever surface you aim the phone at. Zenitum, the South Korean company behind iKat, says the app has to recognize an environment to work:
“Based on Zenitum’s D-Track engine, we are working on markerless mobile augmented reality application, iKat. You are breeding a virtual kitten on the phone. The kitten can be mixed into real world using AR. Since no markers or image targets are needed, you need to recognize the space in front of the camera for creating the appropriate space for your kitten.”
Here’s the app working:
It’s all built using Zenitum′s D-Track software, which is explained in this video below:
iKat is a neat stepping stone for augmented reality, and while the app itself doesn′t do much, I′m sure Zenitum will be expanding their technology for further use. [Zenitum via Recombu]
When planning your next Japan visit, better put aside a night for a “factory night jungle cruise” if you want to be right up there with the latest Japanese otaku craze. They literally visit factories, at night.
According to Japan Trends, which brought the fad to our attention, the “factory love” is popular among photographers—which I can understand, as lit-up factories can be quite scenic—but also families and couples too. A cruise around Panasonic’s factory doesn’t seem quite as romantic to me as cocktails at the top of the Park Hyatt Hotel, but then the 4,500 Yen ($50) cruise ticket price is probably cheaper than a few sake cocktails anyway.

South Korea has overhauled its public transport network with recharging roads, where the vehicles use power from buried electric strips in the road. It was invented at the University of California, before South Korea adopted it for an amusement park.
The system is being tested at an amusement park in Seoul, but if all goes well, the country hopes to expand it to the whole city’s bus route—helping minimize unsightly overhead power lines and obviously doing a good turn for the environment. Dubbed the Online Electric Vehicle system, or OLEV, the magnetic electrical charging strips are buried in four different areas along the 2.2km bus route, with the buses sucking power which can be used to drive or just filling up the battery storage.
When visiting cities like San Francisco that rely heavily on trams, which run on ugly overhead lines, I’ve often thought there should be a better way of networking public transport. This could be the answer—and help a little way towards reducing carbon emissions, too. [PhysOrg]
It’s not a micro four thirds, but Pentax has lifted the lid on the 645D medium format camera, which will be available this May for close to $10,000. Why so expensive, you ask? There’s that 40MP Kodak sensor for starters.
It’s also got a SAFOX IX+ autofocus system with 11 sensor points, a Pentax original Real Image Engine, 14 bit A/D converter, and is the ultimate kick-around camera, with 70 seals making it dustproof, weather resistant and cold-proof. There’s also a dust removal II system, just in case. It takes SD/SDHC memory cards, and while that May release is scheduled for Japan, the rest of the world should be getting some Pentax love soon after. [Photography Blog]

Pentax Press Release
HOYA CORPORATION PENTAX Imaging Systems Division is pleased to announce the launch of the PENTAX 645D lens-interchangeable, medium-format digital SLR camera. Thanks to the incorporation of a large image sensor, equal in performance to professional-standard digital camera backs, this high-performance model delivers super-high-resolution images with approximately 40 effective megapixels. It also offers outstanding dependability and superb operability and maneuverability to make outdoor shooting effortless and comfortable for demanding photographers.
The PENTAX 645D has been developed to provide super-high-resolution images produced by large image sensors - something previously available only on professional models - to serious landscape and outdoor photographers. It combines exceptional image quality with excellent maneuverability and outstanding reliability to simplify professional-level outdoor shooting. Thanks to the incorporation of a large, high-performance image sensor (measuring 44mm by 33mm) and PENTAX-original image-processing technology, it produces extra-sharp, super-high-resolution images with approximately 40 effective megapixels. It features remarkable durability and dependability, thanks to its lightweight but solidly built body featuring a magnesium-steel-alloy frame, reinforced glass LCD panel protectors and a reliable dustproof, weather-resistant construction. In addition, it is designed to be compatible with the majority of the existing PENTAX 645 system, so that current PENTAX 645-series camera users can take advantage of their valuable assets, including high-performance smc PENTAX 645 interchangeable lenses.
Major Features
1. Unprecedented image quality
1. Super-high-resolution images made possible by approximately 40 effective megapixels
The PENTAX 645D incorporates a high-performance CCD image sensor produced by Kodak. It measures 44mm by 33mm, and is approximately 1.7 times larger than its 35mm-format counterparts. Thanks to approximately 40 effective megapixels, it assures a wide dynamic range to faithfully reproduce the prevailing ambience and the sense of depth in super-high-resolution images that are rich in gradation and truthful in texture description. In order to bring out the full potential of the lens and the image sensor and assure the highest level of image-resolving power, the CCD unit is designed with no low-pass filters.
2. High-performance, high-speed PRIME II imaging engine
The PENTAX 645D features the acclaimed, PENTAX-original PRIME (PENTAX Real Image Engine) II as its imaging engine. Thanks to its high-speed data-processing capacity and new algorithm exclusively programmed for medium-format digital SLR cameras, this high-performance imaging engine produces super-high-quality images rich in gradation and faithful in color reproduction, while allowing speedy data transmission of large-volume image data - even RAW-format images as large as some 50MB per file.
3. 14-bit A/D converter for faithful conversion of image data to digital signals
The PENTAX 645D features a high-performance A/D converter, which faithfully converts the large volume of analog image data output by the large CCD image sensor to digital signals carrying an extensive amount of image data, including resolution and gradation.2. Solid, maneuverable body
The PENTAX 645D’s main frame is made of lightweight but strong magnesium-steel alloy, while the chassis is made of diecast aluminum to minimize the expansion and extension caused by heat and also to optimize kinematic accuracy and thermal stability. The LCD panels - one on the camera’s top panel, another on the back panel - are covered with tempered glass plates for extra protection. The PENTAX 645D’s body is also designed to be a compact and highly maneuverable medium-format camera, despite the incorporation of such dependable features as a dust-proof, weather-resistant construction with 70 special seals, outstanding cold-resistant performance to assure solid operation at a temperature as low as –10°C, and a newly designed shutter unit with a top shutter speed of 1/4000 second that can withstand as many as 50,000 shutter releases.3. Dual SD/SDHC memory card slots
The PENTAX 645D has a pair of memory card slots for the recording of images on both SD and SDHC memory cards. This dual-slot design gives the photographer extra data-storage options: for instance, recorded images can be assigned to different cards according to recording format (such as RAW or JPEG), or one of the cards can be used as the backup of the other. The settings for each memory card slot can be easily made by dedicated button.4. Dependable DR II mechanism to minimize dust spots
The PENTAX 645D comes equipped with the highly dependable DR (Dust Removal) II mechanism, which effectively minimizes annoying dust spots on recorded images, even when the lenses are changed in dust-prone outdoor settings. By shifting UV/IR-cut filters placed in front of the CCD image sensor at supersonic speed using a piezoelectric element, this mechanism effectively and efficiently shakes dust off the image sensor. Thanks to the user-friendly dust-alert system, the photographer can check at a quick glance for dust adhering to the image sensor prior to the actual shooting.5. Newly designed, high-precision 11-point wide-frame AF sensor
The PENTAX 645D’s new SAFOX IX + wide-frame autofocus system features 11 sensor points (with nine cross-type sensors positioned in the middle) to assure the extra-high-precision focusing demanded of medium-format digital SLR cameras. To develop this sophisticated AF system, the entire optical system was redesigned, at the same time with the addition of the new functionality to analyze and make use of the light sources data in the field of view.6. Advanced 77-segment multi-pattern metering
The PENTAX 645D employs a state-of-the-art, 77-segment multi-pattern metering system to assure super-high-accuracy light metering. The exposure accuracy is further enhanced by collecting such additional data as image orientation (horizontal or vertical) and the distance to and magnification of the subject using the sensors installed inside the camera body, with the obtained data incorporated into exposure calculations.7. Large, easy-to-see optical viewfinder
Incorporated in the PENTAX 645D’s finder unit, a trapezoid-shaped glass prism not only assures an approximately 98% field of view, but also greatly contributes to the downsizing of the camera body. Coupled with a bright, easy-to-focus Natural-Bright-Matte focusing screen, the PENTAX 645D’s viewfinder offers a large, clear view of the subject.8. Custom Image function to create desired visual effects with ease
The PENTAX 645D’s Custom Image function lets the user easily control an image’s finishing touches to more precisely reflect the user’s creative intentions, or to more faithfully reproduce the ambience of the scene. The user can select one of eight modes, including the new Reversal Film mode designed to create images with the colors that are typical of reversal film. In addition, all parameters - such as saturation, hue, contrast, sharpness, key, and highlight/shadow contrast - can be easily adjusted to desired levels, so that the photographer can shoot images with great ease.9. Versatile, multi-mode exposure system for faithful reproduction of creative intentions
1. Hyper Program function
The PENTAX 645D’s Hyper Program function allows the user to instantly switch from Programmed AE mode to Shutter- or Aperture-Priority AE mode with a simple turn of the electric dials positioned around the grip. A single push of the green button shifts the exposure mode back to the original Programmed AE mode.
2. Hyper Manual function
When shooting in the Metered Manual mode, the PENTAX 645D’s Hyper Manual mode lets the user to instantly set the proper exposure for the subject with a single push of the green button.
3. Sensitivity-Priority mode
The unique Sensitivity-Priority (Sv) mode automatically selects the optimum combination of aperture and shutter speed for the user-selected sensitivity. The sensitivity can be shifted swiftly by electronic dial on the back panel. The variable amount of the ISO could be configured to either 1/2 or 1/3 steps per click.
4. Shutter/Aperture-Priority mode
Taking full advantage of the unique capability of digital cameras for the automatic shifting of sensitivity at any time, the Shutter/Aperture-Priority (TAv) mode automatically selects the most appropriate sensitivity for the user-selected aperture/shutter-speed combination. It allows the user to effortlessly experiment with a greater range of photographic expressions.10. Large, easy-to-view 3.0-inch LCD monitor with approximately 921,000 dots
Positioned on the camera’s back panel, a large 3.0-inch color LCD monitor with approximately 921,000 dots provides a clear, bright view of onscreen images and menus. Since its wide-view design allows quick, effortless confirmation of the monitor image from approximately 170 degrees both horizontally and vertically, the photographer has little difficulty shooting images from low and high angles. The LCD monitor is also treated with exclusive AR (Anti-Reflection) coating to minimize reflections on the screen, even in the outdoor locations under bright sunshine.11. Long battery life
The PENTAX 645D is powered by a large-capacity, rechargeable lithium-ion battery, which can capture approximately 800 images* when fully charged.* Under testing conditions prescribed by PENTAX, when using a rechargeable D-LI90 lithium-ion battery with no flash.
12,. Other features
1. HDR (high dynamic range) function to create one composite image with an extra-wide gradation range from three images with different exposures
2. Dynamic-Range Expansion function to compensate for both whitewashed (excessively overexposed) and blacked-out (excessively underexposed) areas
3. Digital Level function for easy checking of the image’s levels
4. Automatic compensation of distortion and lateral chromatic aberration (available in combination with the D FA 645- and FA 645- series lenses)
5. Versatile white-balance control system, including the CTE mode designed to emphasize the dominant color components of the captured images, which works especially well with such scene like sunset.
6. Mirror shock/operation-noise reduction function to assure smooth, quiet operation of the mirror during shooting
7. Attachment of copyright credits on recorded images
8. Compatible with the SDM (Supersonic Direct-drive Motor) autofocus mechanism, designed to assure smooth, quiet operation using the supersonic motor installed inside SDM lenses
9. HDMI terminal (for type C mini connectors) for high-resolution image data output
10. User-friendly, color-classified control buttons/switches, based on the color universal design concept
11. PENTAX Digital Camera Utility 4 software package, including a RAW-data processing application (based on the popular SILKYPIX RAW-data processing engine developed by Ichikawa Soft Laboratory) and browser applicationHOYA CORPORATION PENTAX Imaging Systems Division is pleased to announce the launch of the smc PENTAX-D FA 645 55mm F2.8 AL[IF] SDM AW. Developed as the first model of the PENTAX-D FA 645 lens series, it not only features new optics optimized for high-quality digital photography to assure exceptional image-description performance, but also provides an image circle covering the image area of existing 645-format film SLR cameras. This unifocal standard lens also comes with a dependable, dust-proof, weather-resistant construction for active outdoor photography.
Major Features
1. State-of-the-art optics to accommodate the requirements for super-high-resolution photography using medium-format digital SLR cameras
Incorporating high-performance, hybrid aspherical optical element in its optics, this new standard lens offers exceptional image-resolving power with outstanding brightness levels even at the edges, while compensating various aberrations to a minimum. All lens characteristics are optimized for digital photography: for instance, flare and ghost images are minimized by applying exclusive lens coatings to optical elements and employing anti-reflection materials for the interior of the lens barrel. As the result, this lens can bring out the full potential of the PENTAX 645D medium-format digital SLR camera.2. Versatile standard lens
When mounted on the PENTAX 645D camera body, this standard lens offers a focal length of 43.5mm (in the 35mm format), which produces an angle of view close to that of the human eye. As the result, it can be used for many different kinds of subjects and applications, including landscapes and portraits.3. Dependable dustproof, weather-resistant construction
Using seven special seals, the lens’ dustproof, weather-resistant construction effectively prevents the intrusion of dust and water to the lens interior. By coupling this lens with the PENTAX 645D camera body, the user is assured of a durable, reliable digital SLR camera system that performs superbly in outdoor settings, even in rain or mist or at locations prone to water splashes or spray. PENTAX plans to use the “AW” (All Weather) designation in the product name of all dustproof, weather-resistant medium-format interchangeable lenses to be marketed in the future.4. Aero Bright coating to dramatically improve image description in backlight
The lens is treated with PENTAX-original Aero Bright coating, which delivers brilliant, high-quality images by preventing annoying flare and ghost images more effectively than ever before. Born as the fruit of PENTAX’s advanced nanotechnology, this exclusive coating effectively reduces lens reflectance and greatly increases light transmittance by forming a silica aerogel layer with uniform pores on the surface of optical element.5. Rounded diaphragm to produce a beautiful bokeh
This is the first PENTAX medium-format interchangeable lens to features a completely rounded diaphragm. It creates a natural, beautiful “bokeh” (out-of-focus rendition), while minimizing the streaking effect of point light sources.6. Smooth, quiet SDM autofocus mechanism
The SDM (Supersonic Direct-drive Motor) autofocus mechanism operates smoothly and quietly using the supersonic motor installed inside the lens barrel.** Only manual-focus operation is available when this lens is mounted on the PENTAX 645N or PENTAX 645N II camera body.
7. SP coating to block dust and dirt
The front surface of the lens is treated with PENTAX-original SP (Special Protect) coating, which applies an exclusive fluorine compound to the lens surface through a vapor deposition process. This SP coating not only effectively repels dust, water and grease, but also makes it easy to wipe off fingerprints and cosmetics.8. Other features
1. Image circle covering the image area of 645-format film SLR cameras
2. Functional, simplified design, with no aperture ring
3. Quick-Shift Focus system for instant switching to manual-focus operation, after the subject is captured in focus by the AF system
4. PL filter window for easy installation of a polarizing filter without removing the lens hood
5. PH-SA67 Square Plastic Hood (optional)** for more effective prevention of flare and ghost images when mounted on the PENTAX 645D camera body** This hood cannot be used with a 645-format film SLR camera body, as it causes vignetting.
