Overview
  • 1Description

Sony's Alpha DSLR-A900 SLR Digital Camera (Body Only), their first "full frame" model, has alerted the industry and consumers in the DSLR world that they're in the digital SLR camera business for the long haul.

The DSLR-A900 starts with a 24 x 35.9mm size CMOS sensor developed especially for this camera.  Though that imaging canvas is utterly packed with pixels, the pixels themselves dominate the landscape of the image receiving area, instead of the elements of image sensors which are necessary but not actually collecting the image.  Indeed, the A900's pixels are larger than the fine consumer-grade Alpha 700, despite having twice as many pixels.

On the physical side of things, the Alpha's designed for professional use:  all operations are weather-sealed, its high-performance shutter's tested to 100,000 cycles, and its viewfinder (the forgotten critical SLR element in the age of squinty APS-C size viewfinder dominance) is as good as they come.  Despite these claims, together with batteries and a memory card it tips the scales at ~2 lbs (900g), a good competitive number especially considering the enjoyable view.

Beyond physical elements, the DSLR-A900's got plenty of brains. To speed up throughput for pro sports and action use, Sony's employed dual "Bionz" image processors. Its two analog-to-digital engines swallow large chunks of information, shoving up to ~5 frames per second into a fast memory card-quite bold capacity considering those big RAW files.

With its image quality, handling ease, robust construction, and brilliant viewfinder, the DSLR-A900 should prove a serious tool for professionals and advanced consumers. The benefits of 'full frame' are plentiful; better dynamic range, more natural skin rendition, a cushy viewing experience and superior capacity to blur backgrounds. Super wide angle zooms start at focal lengths more befitting professional instruments, and are awash upon the secondhand market.

35mm-Style "Full Frame" 24.6MP Exmor CMOS Sensor
The 35.9 x 24mm 35mm-size "Exmor" CMOS image sensor is ~2.35x larger than typical APS-C size sensors, and the large capture area affords more sharpness, tonal graduation, and depth of field control. Best of all, pixels themselves dominate the square footage.
World-Class Viewfinder
Glass pentaprism optical viewfinder with 100% coverage, 0.74x magnification, and 20mm eye relief. Low magnification makes the composition canvas small, distant, and unengaging. High magnification makes a viewfinder's eye relief impossibly short for eyeglass users. Getting both right gives an ideal conduit between ideas and images. Though tough to have long eye relief and full coverage without obnoxiously large glass atop an SLR, Sony's succeeded here. Beyond the numbers, the brightness, size, and viewing comfort of this viewfinder returns to the forefront the primary element of camera/user interaction. There's also a built-in shutter blind and integrated -3 to +1 dioptric correction, and bringing it to the eye disengages the LCD screen.
Professional Construction
Weather, dust, and impact sealing befits a professional SLR, and the DSLR-A900's carbon fiber shutter is high-specification; tested for a min. 100,000 cycles, its 1/8000th second top speed and flash sync with any flash at 1/250th second (1/200th with stabilizer activated) display its manufacturing strength.
Full Frame "SteadyShot INSIDE" Stabilization
Alpha 900's in-camera stabilization redefines common belief; a steadying effect of ~4 shutter speed steps, but with a full frame. Previous in-camera stabilizing corrected movements of ~15x22mm image receiving areas within 24 x 36mm 'full frame' confines, as full frame in-camera correction was believed to result in wider, taller, and thicker housings. At 6.1 x 4.6 x 3.2" (156 x 117 x 82mm), it isn't too big a camera-a little thick, but within professional DSLR standards. The stabilizer works with every mounted lens, instead of being an expensive and occasional component within lenses. As with all stabilizers, they don't speed shutters-only more light, higher ISOs, or larger apertures can do that. Stabilizers benefit typical low light pics as well as handling monster telephoto lenses.
