Review based on a production Nikon D80 
Two and a half years ago Nikon announced the six megapixel D70, their first affordable enthusiasts digital SLR, it proved to be a very popular camera and strong competitor to the Canon EOS 300D (Digital Rebel). Just fifteen months later Nikon revealed the D70s which was essentially the same camera with a some subtle tweaks (improved AF, wider flash coverage, higher capacity battery, larger LCD monitor). And so just over fifteen months on from the D70s Nikon present the latest incarnation of their 'enthusiasts' digital SLR line, the ten megapixel D80. The D80 slots nicely between the entry-level D50 and the semi-professional / professional D200, clearly based on the D70 design but also different enough to be seen as a completely new model. It features a ten megapixel DX format CCD (the same we presume as used by Sony in the DSLR-A100), the metering sensor from the D50 and numerous other items taken or modified from the D200. UPDATE 18/Dec/06: In our original review a mistake was made in the measurement of the ISO sensitivity of the Canon EOS 400D as used for comparison, this has now been corrected and the releveant pages of this review updated. Key features 
10.2 megapixel DX format CCD (1.5x FOV crop)  Image processing engine (similar to D200 / D2X) 3D Color Matrix Metering II, 420 pixel sensor (same as D50)  11-area AF system (new version of Multi-CAM 1000, similar to D200) Custom Auto ISO (selectable maximum ISO, minimum shutter speed) Configurable high ISO and long exposure noise reduction Mechanical only shutter (maximum 1/4000 sec, flash sync to 1/200 sec)  Quoted 80 ms shutter lag (short viewfinder blackout; 160 ms)  Larger, brighter pentaprism viewfinder (x0.94 magnification)  Support for SD-HC (SD cards over 2 GB in capacity)  In-camera retouching  D-Lighting (shadow / highlight enhancement) Red-eye reduction Trimming Monochrome Filter effects  Small picture Image overlay  Multiple-exposures Compact body (smaller, lighter than D70/D70s)  Improved menu user interface (same as D200) Higher capacity EN-EL3e battery (provides detailed information, same as D200) Wireless flash integration (same as D200)  Compared to the Nikon D70s, major feature and specification differences  &nbsp;

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 that 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 in the evolution of this line of cameras. Whilst the core values of a high quality full-size body with integrated grip have remained constant, the line split into two halves (indicated by the X and H suffixes), one targeted at high resolution photography the other high speed sports type photography (lower resolution but faster continuous shooting). It's been almost three years since Nikon introduced a completely new digital SLR with a new sensor (the D2X) and there had been much anticipation that Nikon's next move would be a full-frame chip. And so it was, with the introduction last August of the new 'FX format' D3, featuring 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) with automatic cropping 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). Our first comment on seeing the D3 in the late summer of last year was 'where's the 'H' suffix?', something echoed many times in the months following announcement by commentators and photographers. Although Nikon remains tight-lipped about its future plans it seems fair to assume that Photokina will bring an EOS 1DS Mark III competitor (with higher resolution but without the high speed shooting). Note: The day this review was finished Nikon announced a firmware upgrade for the D3, which added a couple of new features (including vignette correction and control over the brightness of the AF points) and a few bug fixes. Today Nikon pulled the upgrade as in certain circumstances (shooting at maximum speed in 14-bit RAW mode) it can 'in rare circumstances' cause corruption of some images. We updated the firmware on our test D3 yesterday and have not been able to recreate the issue, though many of our forum members have. 99% of this review was done with the original (v1.00) firmware.

 Review based on a production Canon EOS 40D 
The EOS 40D becomes the sixth Canon 'prosumer' digital SLR, a line which started back in 2000 with the EOS D30, and how far we've come. It's been eighteen months since the EOS 30D and although on the surface the 40D looks like a fairly subtle upgrade there's a lot that makes this an even better camera. Of course we expect a step up in megapixels, and so the 40D comes with a ten million pixel CMOS sensor with the same sort of dust reduction as the EOS 400D, an ultrasonic platform which shakes the low pass filter. Other improvements bring the EOS 40D closer into line with the EOS-1D series, these include a move to the same page-by-page menu system, both RAW and sRAW (2.5 MP), 14-bit A/D converter and 14-bit RAW, cross-type AF points for F5.6 or faster lenses, a larger and brighter viewfinder, interchangeable focusing screens, a larger LCD monitor (3.0") and faster continuous shooting (6.5 fps).

Just under two years since the D200 Nikon reveals the D300, the range of changes is so significant that it wouldn't be inappropriate to call it a 'compact D3' (less the full-frame sensor of course). From the top there's a new CMOS sensor with twelve megapixels, a new auto-focus sensor with 51-points (15 of which are cross-type sensitive), there's focus tracking by color, scene recognition, Picture Control presets, six frames per second continuous shooting (or eight frames per second with a battery pack), Compact Flash UDMA support, Live View (with contrast detect AF) and the mighty impressive 3.0" 922,000 pixel LCD monitor (oh and HDMI video output). It's an impressive list, the D200 was a fair step up from the D100, the D300 can be seen as just as big a step, certainly more than enough to make the competition sweat.  Nikon D300 Key Features
