Digital Camera Description

The Sony Alpha A900 is a Professional DSLR with a Full-Frame sensor and a Sony A lens mount. Its 25 Megapixels CMOS sensor offers an ISO 200-3200 sensitivity range which is expandable to ISO 100-6400. This makes it possible to shoot hand-held in relatively low-light. With 25 MP of resolution, sharp prints are possible up to 26" x 17" at 240 DPI.

A builtin 2-Axis Image Stabilization mechanism allows the Sony Alpha A900 to compensate for camera shake up to 2.5-Stops beyond hand-holding with any mounted lens.

This camera features a mechanic shutter that can expose for 1/8000 to 30s. Bulb exposures of an unspecified duration are possible with this camera. With a fastest shutter-speed of 1/8000, fast action can easily be frozen. Night photography is possible using this digital camera due to its long exposure capability. This camera model offers Full Manual Controls.

The Sony Alpha A900 features a 9-point Phase-Detect AF system. Autofocus can continuously adjust according to subject distance. Manual Focus is also available.
