Along with the a550 and a500, Sony introduces the Alpha a850 full-frame DSLR camera that shares the same 24.6 megapixel sensor and most features of the flagship a900 DSLR camera.

Sony introduces the new Alpha a550 and a500 digital SLR cameras to its Alpha DSLR line, both feature Sony’s Exmor CMOS image sensor and BIONZ image processor with color-noise reduction. The 14.2 Megapixel a550 and 12.3 Megapixel a500 both offer ISO sensitivity up to 12800.

Sony Alpha DSLR-A900 is the company’s latest full-frame digital SLR camera. It features a 24.6 Megapixel 35mm Full Frame CMOS image sensor, ISO from 100 to 6400, High Speed Dual BIONZ image processor, and a 3-inch LCD display. It supports direct HDMI output. The Alpha A900 uses CompactFlash and Memory Stick cards.

Sony Alpha DSLR-A900 has been reviewed by DPReview:
In conclusion this is, more than anything else at this end of the market, a true photographer’s camera, with at least one totally unique feature (the Super SteadyShot stabilization) and one that offers the best viewfinder and highest nominal resolution (and the lowest ‘cost per megapixel, incidentally) in its class.

Sony officially introduces its new Alpha A900, which is the world’s first DSLR to have a 24.6 effective Megapixel full-frame CMOS sensor. Sony A900 is equipped with dual Sony BIONZ image processors for razor-sharp shooting responses, and outstanding image quality.

This is the Sony Alpha A700 digital SLR camera. A700 features a 13 Megapixel ‘Exmor’ CMOS sensor, an ISO rating up to 6400 and a 3-inch LCD display. It supports CCD-shift dust reduction, Noise reduction and the Super ‘SteadyShot’ system.
Interestingly the one thing the A700 doesn’t have is any form of live view; when we spoke to Sony about this the answer was simple; they believe that the compromises involved in current systems are unsatisfactory, and they won’t implement live view until they can ‘get it right’. Whether the lack of live view has any real relevance in a camera at this level remains to be seen; we doubt it.
