This baby has been cropping up at shows and on enthusiast Web sites all summer but now Sony has finally announced the A900, the company's first full-frame digital Single Lens Reflex (DSLR) camera. It's also the industry's first with a 24.6 effective megapixel full-frame CMOS sensor and is capable of shooting 5fps at full resolution. This well appointed snapper edges into the professional arena but will no doubt excite well-heeled amateur enthusiasts too. It performs on-chip analogue/digital (A/D) signal conversion and two-stage noise reduction while the glass optical pentaprism viewfinder is very bright and offers a field of view covering 100% of the full-frame sensor's imaging area. There's a 9-point Auto Focus system to ensure fewer missed shots, supported by 10 focus assist points. The A900 is also the first full-frame camera to sport SteadyShot INSIDE, which delivers up to 4 steps of anti-shake correction so that all your ugly relatives will always look their best. The Intelligent Preview feature is pretty cool as it lets you take a 'preview shot' stored in temporary memory but displayed on the LCD display which you can apply various effects to before taking the final snap, which will replace the tweaked temporary shot. There's a 3in LCD display and a HDMI slot for viewing your photos on HDTVs. It supports both CompactFlash and MemoryStick cards - a good thing when you consider that a single, full 24MP uncompressed shot can be over 20Mb. It's due out next month and has a US price of around £1,700, but expect that to creep up magically as it crosses the Atlantic.-Martin Lynch photo camera photography
