Sony has announced its first full-frame alpha DSLR-A900 camera, designed to deliver picture quality at 24.6 megapixels through a 35mm full-frame Exmor CMOS sensor and fast image processing with a new dual Bionz processing engine. The camera will also have a body-integrated image stabilization system for a full-frame sensor with Sony's SteadyShot Inside anti-shake system.

The camera's body-integrated SteadyShot Inside unit achieves an anti-shake effect equivalent to shutter speeds faster by 2.5 to 4 stops, while its viewfinder features a 100 percent field of view coverage and 0.74x magnification. The A900 features a high-power condenser lens, an eyepiece with high-reflective-index glass, and a multilayer, anti-reflective coating on every optical surface.

The camera's newly developed autofocus system consists of nine wide-area sensors with 10 assist points for improved tracking of moving subjects. A center dual-cross sensor composed of two horizontal- and two vertical-line sensors and an f/2.8 sensor also allow for greater precision when using fast-aperture lenses.

Users can fine-tune white balance, determine the best level and effect of dynamic range optimization, adjust exposure compensation and check histogram data before taking the picture. Other key features aimed at expanding creative options include the Dynamic Range Optimizer (DRO) with five levels of user-selectable correction as well as DRO bracketing for enhanced scene analysis and graduation optimization. EV bracketing with ±2EV range makes it easy to create high-dynamic-range composite images. High-speed continuous shooting of 24.6-megapixel images is capable at five frames per second (fps).

Thirteen creative styles and as many as 26 different mode settings offer users a variety of choices. RAW file processing is made possible with the Image Data Converter SR3 software.

The DSLR-A900 body will be available in November for about $3,000.
