The Sony A900 digital SLR from Sony sets a new benchmark for serious photo enthusiasts who demand the unrivalled quality and creative possibilities of full-frame imaging. The flagship of the Alpha DSLR range features the industry’s first ever 24.6 effective megapixel full-frame CMOS sensor. Developed by Sony, this groundbreaking sensor’s ultra-high pixel count and large size - equivalent to a 35mm film frame - deliver extraordinary image detail and wide dynamic range.

The new-generation sensor captures flawless images with unprecedented fidelity, characterized by vibrant colours, ultra-real textures and subtle tonal gradations. Complementing the extremely high native resolution of the sensor, Exmor performs on-chip analogue/digital (A/D) signal conversion and two-stage noise reduction. This guarantees ultra-low noise image files that take advantage of the superb resolving power of high-precision α lenses. Realising the immense creative potential of the 24.6 MP full-frame sensor, the new advanced dual BIONZ processors handle massive amounts of image data at extremely high speed. Powerful noise reduction algorithms are applied prior to RAW data conversion and then again during image processing, yielding flawless, detail packed images with an absolute minimum of noise. The dual BIONZ processors also underpin the camera’s razor-sharp shooting responses, allowing sustained 5fps continuous shooting at full 24.6 megapixel resolution.
