Canon's 8 megapixel EOS 20D has been replaced by the new 30D, but some will be disappointed to learn the new model adopts the same 8.2 CMOS sensor originally designed for its predecessor. That aside, the new model has been brought into line with Canon's other recent releases, namely the 12.8MP full-frame EOS 5D and 8.2MP EOS 1D MkII N. All three now feature a detailed 230K pixel 2.5in monitor, spot metering and Canon's intuitive Picture Styles for predictable in-camera image processing. Elsewhere, the 30D has seen numerous tweaks including a more durable shutter mechanism, capable of 100,000 releases, as well as subtly remodelled magnesium alloy body.
Like the outgoing model, the EOS 30D is considerably larger and heavier at 700g (body only) than the entry-level EOS 350D, although if you're looking to upgrade, you should find improvements in the general layout and ergonomics. A control panel is on the top plate rather than positioned above the screen, and it is arguably better suited for everyday use. It's certainly more comfortable when being used on a tripod in a studio. Even so, we found it quite small compared to that on the rival Nikon D200, and especially the analogue scale used for manual exposure and compensation. It's the same story in the viewfinder and although ISO settings aren't on permanent display there, they are shown when being changed.
Standard sensitivity runs from ISO100-1600, in third stops, and all are useable thanks to the low-noise characteristics of Canon's proprietary CMOS sensor technology. An extended (H) setting, equivalent to IS03200, is welcome, and although noise levels are the lowest in its class, pictures are still pretty grainy. A number of noise reduction options are offered, including a quality orientated workflow with both chrominance and luminance noise reduction in the latest version of Canon's Raw file processor, Digital Photo Professional. Although conversion is tardy, it's bundled free of restriction, as is Canon's handy EOS utility, offering remote control and capture with a tethered camera.
Arguably the most significant change is the adoption of Canon's now standardised Picture Styles with its set of six subject-based parameter options. Offering a range of settings for sharpness, contrast saturation and colour tone, each can be fine-tuned to suit, or you can customise and store a further three presets for various subjects. Interestingly, if you have a 5D or 1D MkIIN, then the colour response for any of the default presets is claimed to be identical - useful if you regularly switch between bodies. You are also far less likely to be confused by the new arrangement and a custom option using the rear control dial for selection is completely fuss-free.
Shooting action or sports with a choice of either three or five frames per second is achieved with consummate ease. Nine focus points can keep track of moving objects while accurately adjusting focus; although each are lit, they're quite small compared to most rivals. Like most rivals, simultaneous Camera Raw and Jpeg capture has been expanded and although buffering has been improved in the 30D, it is still only reasonably generous. Up to eight high-quality Jpegs and Raw files can be captured together without faltering, although single format capture is significantly better. However, while we appreciate the larger screen and its clarity, it fades even in moderate sunlight.
Picture quality, while not above criticism, is certainly impressive. We've no real complaints with metering or colour accuracy outdoors, and the auto white balance handles indoor lighting very well. Colour casts aren't as heavy as most rivals, and there's been some improvement over the 20D. Chromatic aberration using the 18-55mm starter lens is noticeable in some shots, predominantly at the edges rather than the centre. Still, the 30D can be bought body-only if you're adding it to a system. As an upgrade to the 20D, there's little to warrant to moving up, although if you have the 350D, you may find the expanded manual control and faster framing rates beneficial. The 30D isn't a better camera than the excellent Nikon D200, although there isn't a great deal between them in everyday use. However, given its price online, the 30D is certainly outstanding value.
