Excerpt: There was really no good reason for Canon to replace the EOS 20D. And so, commendably, it didn't. The new EOS 30D ($1,400 street, body only) might well be considered a "20D II" or a "20DN," given that it uses the same 8MP CMOS sensor, processing engine, viewfinder system, chassis, and control layout...
Conclusion: Canon EOS 30D digital SLR camera With the arrival of the Canon EOS 30D model, we see Canon's fifth introduction in the popular D-SLR middle segment. It is admittedly somewhat confusing that its name is virtually identical to that of the first type: the Canon EOS D30.
Excerpt: Overall not a bad camera. I've used it at ~18,000 ft down to ~-10 degrees F without any problems. This is a minor revision to the previous model, the 20d so not a whole lot has changed. I kind of wish canon had upped the resolution a bit, but it's still a great camera.
Summary: Canon EOS 30D verdict
When Canon announced the EOS 30D would employ the same sensor as its predecessor, it was hard not to be both surprised and a little disappointed. After all, for its previous generations of digital SLRs, Canon lead the market by always developing new, higher resolution sensors.
Pros: Low noise, high quality images, Good build quality and handling, 5fps continuous shooting, 2.5in screen and spot-metering
Cons: Not a big step-up from the 20D, No voice recording, No GPS connectivity, Nikon D200 a tempting alternative
Summary: As a new camera the Canon EOS 30D is a bit of a disappointment, but viewed as an upgrade to an already very good camera, it performs its role well. So while the extra functions don’t excite us as much as a brand new model would, the Canon 30D is still a very good camera.
Pros: Build quality, LCD, menu system, low noise, high specifications
Cons: Images need some post processing to reduce flat look, aperture/exposure compensation system, depth of preview button in wrong place
Summary: The EOS 30D Digital SLR is the much anticipated update to Canon's popular . It takes the same 8.2-megapixel APS-C size CMOS sensor and mates it to the more powerful DIGIC II Imaging processor for fast 5 fps performance.
Conclusion: Maybe Canon do listen, with the i EOS 30D they have addressed no less than five of the 'Cons' from my EOS 20D review; Lack of spot metering, Fixed continuous shooting rate, Limited range of image parameter adjustment, Small LCD monitor and ISO sensitivity not displayed on viewfinder status bar while...
Pros: Excellent resolution, very good per-pixel sharpness, Good tonal and color response, same as EOS 20D 'Parameter 1' in Standard PS, Now with four metering modes, spot metering very welcome, Trademark Canon CMOS noise free images, remain detailed even at high sensitivities, About a third of a stop m...
Cons: Average automatic white balance performance, still very poor under incandescent light, AI Servo (continuous AF) interference banding issue (certain lenses, high sensitivities), Same old 'CF compartment door shuts camera down' issue, Picture Style differences between RAW Image Task/Camera and DPP,...
Excerpt: The Canon EOS-30D is one of those cameras that's evolutionary, rather than revolutionary. It updates the very popular EOS-20D (see our review), though the new features are more "I wouldn't mind having that" than "I've gotta have that!".
Pros: Excellent photo quality (with the right lenses), Very low noise, even at high ISOs, Solid, well designed body; useful playback zoom buttons, Large 2.5" LCD display, Full manual controls, including nice white balance controls, Robust performance, especially in terms of continuous shooting, Great l...
Cons: Images on the soft side straight out of the camera; some lenses just exacerbate the problem, LCD not as bright/sharp as the one on the Nikon D200
