Overview — Sony DSLR-A900

The Sony DSLR-A900 is a full-frame DSLR built around a 24.6MP sensor, delivering a maximum resolution of 6048x4032 pixels. Image processing is handled by a Dual BIONZ engine, which works in tandem with that high-resolution sensor to manage the data throughput demanded by large files. The ISO range runs from 100 to 6400, giving shooters a practical spread for controlled and lower-light environments.

In-body sensor-shift image stabilization is included, meaning any compatible Sony A-mount lens can benefit from stabilization without requiring optically stabilized glass. The autofocus system uses phase detection with 9 focus points. Continuous shooting reaches up to 5 frames per second, making it capable for action and event work.

The 3.0-inch LCD display resolves 921,600 dots, which was a notably sharp screen for its era. An optical viewfinder is on board. Storage options span both CompactFlash and Memory Stick Duo slots.

The body is constructed from magnesium alloy and measures 156 x 117 x 82 mm at a weight of 850g. Connectivity includes USB and Mini HDMI output. The camera uses an NP-FM500H battery rated at 880 shots per charge and mounts lenses via the Sony A mount with a Sony Auto-lock Shoe for flash.

Key Features — Sony DSLR-A900

24.6MP Full-Frame Sensor: Delivers a maximum resolution of 6048x4032 pixels, suitable for large prints and significant post-crop flexibility.

Dual BIONZ Processing: Twin image processors handle the high data throughput demanded by a full-frame, high-resolution sensor for faster file processing.

Sensor-Shift IBIS: In-body stabilization works with any Sony A-mount lens, so stabilization is not dependent on optically stabilized glass.

ISO 100–6400 Range: Provides a practical sensitivity spread for well-lit through lower-light shooting conditions.

9-Point Phase Detection AF: Phase detection autofocus system for reliable subject acquisition, particularly suited to static and moderately active subjects.

5fps Continuous Shooting: Burst mode at up to 5 frames per second for capturing fast-moving subjects at events or in the field.

Description — Sony DSLR-A900

The Sony DSLR-A900 centers on a full-frame 24.6MP sensor capable of capturing images at 6048x4032 pixels, processed through a Dual BIONZ engine that handles the substantial data output of a high-resolution full-frame file. The ISO range spans 100 to 6400, and continuous shooting reaches 5 fps for burst capture. Autofocus relies on a phase detection system with 9 focus points.

One of the A900's standout features is its sensor-shift in-body image stabilization, which benefits any lens mounted via the Sony A mount — no optically stabilized lens is required. The 3.0-inch LCD resolves 921,600 dots for detailed playback, complemented by an optical viewfinder. The body is built from magnesium alloy, measuring 156 x 117 x 82 mm and weighing 850g.

Storage covers both CompactFlash and Memory Stick Duo formats. Output connectivity includes USB and Mini HDMI. The camera runs on an NP-FM500H battery rated at 880 shots.

Note that this camera has no video recording capability, no weather sealing, and no wireless connectivity.
