At the top of the α (alpha) lighting system, the new HVL-F58AM flash allows the head to pivot 90 left or right maintaining correct camera/flash orientation during both horizontal and vertical shooting.
HVL-F58AM can control sophisticated multi-flash off-camera setups, comprising up to 3 flash groups, with flash ratio balance among groups to achieve creative lighting results.
PhotoTV HD is a new way to view photos which brings out radiant beauty in every detail, filling the room with luminous, high-resolution images that more closely matches the natural look of printed photographs.
The new standard in digital photography has arrived with the Sony α DSLR-A900. Packed with features, this flagship DSLR is the first α to incorporate a 35mm full frame image sensor and 24.6-megapixel resolution. It also incorporates the world's first body-integrated, full-size SteadyShot INSIDE™ image stabilization technology.You'll also experience a larger capture area, improved wide-angle performance and tighter depth of field control with the new full frame Exmor™ CMOS image sensor. Equipped with Dual BIONZ™ imaging processors, the α900 delivers continuous shooting up to 5 fps with superb image quality and ultra-low noise. The α900 also offers a large, ultra-bright glass pentaprism viewfinder with 100 percent coverage, a 3.0-inch Xtra Fine LCD™ display and HDMI™ output with PhotoTV HD compatibility. The DSLR-A900 is a camera body only and does not include a lens.
Note: Sony α (alpha) lenses with the Digital Technology (DT) designation are not recommended for use with DSLR-A900. Although DT lenses can be used with α900, they can only realize a maximum of 11MP image size, and are not guaranteed to provide accurate Auto Exposure performance.
The A900 features a 35mm full frame Exmor™ CMOS image sensor that is approximately 2.35x larger than the APS-C sized sensors found in many DSLR cameras. The result is a larger capture area, improved wide angle performance, and tighter depth of field control. In addition, its 24.6MP resolution maximizes the resolving power of your existing lenses and delivers sharper, higher contrast photos.
A large, ultra bright glass pentaprism viewfinder provides you with amazing clarity and high optical performance for tighter focus control. In addition, it offers viewfinder magnification of 0.74x, allowing you to see an image nearer to its actual size, as well as 100% field coverage for detailed framing work.
The A900 provides direct HDMI™ output to your BRAVIA® HDTV and other compatible HDTV screens, so you can view and share photos in breathtaking clarity and detail3. Additionally, PhotoTV HD capable BRAVIA® HDTVs will automatically optimize display settings, such as sharpness, gradation, and color to display your images in a way that more closely matches the natural look of printed photographs3.
The body of the A900 is entirely covered in a die-cast magnesium alloy shell, providing a rugged feel and surprisingly lightweight.
A supplied InfoLITHIUM® lithium-ion battery provides long-lasting performance, allowing you to capture approximately 880 images on a single charge7.
A 40-segment multi-pattern metering system provides superior exposure control accuracy in a wide range of lighting conditions.
In addition to digitizing analog signals, the full frame Exmor™ CMOS image sensor also performs both analog and digital noise reduction. This on-chip dual noise reduction process aids in the high speed transfer of noiseless digital signals.
In addition to full frame image capture, the A900 can also crop images to the APS-C size format, allowing the use of lenses designed specifically for APS-C sized image sensors5.
AF Micro Adjustment allows you to fine tune focus for various lenses6. The A900 can store adjusted focus values for up to thirty lenses.
The A900 allows you to bracket up to three exposures in 2.0EV-step increments.
Remote Camera Control allows you to control your A900 from your PC.
The A900 harnesses the power of Dual BIONZ™ image processing engines to deliver true-to-life images with ultra-low noise and continuous shooting at up to 5 fps.
Review your images in stunning detail on the 3.0” Xtra Fine LCD™2 display (921k pixels). With photo-quality resolution of 270ppi (pixels per inch), you can identify any necessary focus or exposure corrections at the time of capture, rather than discovering them when you transfer your images to your PC.
The A900 features an impressive design befitting a premium flagship model. The simple form eschews ornamentation and exudes competence, while the iconic pentaprism design element conveys superior optical performance. The A900 also incorporates a distinctive cinnabar-colored ring circling the lens mount – a design element shared across every Sony® α; (alpha) DSLR camera.
Changing lenses in a DSLR can allow dust to enter the camera -- so to help keep the CMOS imager cleaner for better pictures, the Sony® α; (alpha) DSLR-A900 utilizes both static-free anti-dust coating on the imager's filter and anti-dust vibration that automatically shakes the sensor to dislodge dust each time the camera is shut off.
The A900 features a dual card slots and accepts both CompactFlash® and Memory Stick Duo™ Media (sold separately).
Analog-to-digital signal conversion is performed by the full frame Exmor™ CMOS image sensor.
Updated Image Data Converter SR3 software4 improves your workflow with faster RAW file processing and improved image correction.
The A900 includes a built-in eyepiece shutter which can be shut to help shield against entering light and prevent exposure errors.
Mirror Lockup Mode raises the main mirror before exposure to reduce vibration at shutter release, resulting in better performance during long exposure shots of fireworks, stars, etc.
The Image Data Lightbox software4 included with your Sony® α; (alpha) DSLR helps you browse, rate, and compare your images, making it easier to select your favorites for further processing.
Concentrate on your shooting and make adjustments on the fly thanks to convenient button placement. The ISO and White Balance adjustment buttons are located on the top of the camera body near the shutter button for easy thumb operation.
Building on years of expertise, Sony has developed the world’s first body-integrated image stabilization solution for a full frame DSLR1. The SteadyShot INSIDE™ in-camera image stabilizer actually shifts the image sensor to compensate for camera shake without sacrificing image quality. The compensation effect is equal to as many as four shutter speed steps, giving you more creative freedom when shooting in low light. And, because it is integrated into the camera body, SteadyShot INSIDE technology works with all compatible α (alpha) system lenses.
The Intelligent Preview function allows you to see the effects of manual adjustments to exposure value, shutter speed, aperture, Dynamic Range Optimizer and White Balance before you take the shot, so you can determine the optimum settings before you take the shot, instead of losing time to trial-and-error.
A high-performance autofocus system uses 9 focus points (center dual-cross type) and 10 assist points to deliver fast and precise focusing.
Sealed viewfinder optics and rubber gasket surrounds on all buttons, dials, and switches help resist the entry of dust and moisture into the camera, and allow for safe use in a wide range of environments.
The shutter mechanism in the A900 is designed to achieve shutter speeds up to 1/8000 seconds and proven for 100,000 cycle operation.
To recover details in dark or bright areas of the image, the A900 provides multiple levels of Dynamic Range Optimization: Standard mode, to improve shadow detail using standard gamma curves; Advanced Auto mode, allowing you to select any of 5 DRO correction levels, or DRO Advanced Bracketing, which automatically takes three shots at different DRO levels with a single shutter press.
The autofocus system in the A900 features a highly accurate F2.8 sensor for improved focus precision when using lenses faster than F2.8.
Viewfinder magnification of 0.74x lets you see your subjects nearer to actual size.
User-replaceable focusing screens for shooting specific subject types can be purchased as optional accessories.
Sony drew upon its extensive experience designing and building heavy professional broadcasting camcorders to develop a rubberized grip that allows you to hold the A900 with comfort and confidence.
Sony® Picture Motion Browser (PMB) software4 provides a simple and intuitive way to sort and archive your image collection, as well as perform common editing operations and output to data disc or the Web.
