SONY DSLR-A900

Download SONY A900 brochureSONY DSLR-A900

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 alpha A900 delivers continuous shooting up to 5 fps with superb image quality and ultra-low noise. The A900 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 A900, they can only realize a maximum of 11MP image size, and are not guaranteed to provide accurate Auto Exposure performance.

More Features

  • 35mm full frame 24.6MP Exmor™ CMOS image sensor:

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.

  • SteadyShot INSIDE™ in-camera image stabilization:

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.

  • Dual BIONZ™ processors for up to fast 5fps performance:

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.

  • Ultra bright, 100% coverage glass pentaprism viewfinder

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.

  • Intelligent Preview Function

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.

  • 3.0" Xtra Fine LCD™2 (921K pixels)

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.

  • PhotoTV HD viewing w/ HDMI™ output

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.

  • Precise and fast 9-point AF system w/ 10 point assist

A high-performance autofocus system uses 9 focus points (center dual-cross type) and 10 assist points to deliver fast and precise focusing.

  • Flagship design

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.

  • Rugged magnesium alloy shell

The body of the A900 is entirely covered in a die-cast magnesium alloy shell, providing a rugged feel and surprisingly lightweight.
