Nikon D3 Preview

Nikon D3 Preview
The professional Nikon D 'single digit' series of digital SLR's started life back in June 1999 with the groundbreaking D1. Groundbreaking because it was the digital SLR which broke Kodak's stranglehold on the digital SLR market and fundamentally brought prices down to a level which most professionals could afford (around the US$5,500 mark). Since then we have seen a steady progression of this line of cameras, while the core values of a high quality full size body with integrated grip have remained the line split into two halves, one targeted at high resolution photography the other high speed sports type photography (lower resolution but faster continuous shooting); the X and H suffixes. It's been almost three years since Nikon introduced a completely new digital SLR with a new sensor (the D2X) and there has been much anticipation that Nikon's next move would be a full-frame chip.
This predictions have come true with the introduction of the 'FX format' (new moniker created by Nikon) D3 which features a 36 x 23.9 mm 12.1 megapixel CMOS sensor as well as a vast array of new features which absolutely raise it another notch above previous single digit Nikon DSLRs. Important headline improvements include high sensitivity support by default, up to ISO 6400 with 25600 available as a boost option, 14-bit A/D conversion, a new standard image processor, a new shutter, new auto focus sensor, focus tracking by color, nine frames per second continuous, dual compact flash support, DX lens support (albeit at lower resolution) and a 3.0" 922,000 pixel LCD monitor (which it has to be said is lovely).
Some will undoubtedly question Nikon for 'only' delivering twelve megapixels on their first full frame digital SLR, all we can presume by looking at past model line history is that this camera is designed for speed (both in sensitivity, auto-focus and continuous shooting).
