Canon EOS 30D
Simply put, the EOS 30D reset the expectations of SLR buyers in 2006. It incorporates features with Canon’s acclaimed 8.2 megapixel CMOS sensor and DIGIC II Image Processor. Enhancements include a 2.5 inch LCD monitor, true spot metering, a durable shutter mechanism, a sturdy magnesium-clad body, and Picture Style, which aims to produce polished output without the need for adjustments in a program such as Photoshop.
The 30D was supplanted in the Canon lineup by the 40D in 2007.

The Canon EOS-30D is one of those cameras that’s evolutionary, rather than revolutionary. It updates the very popular EOS-20D, though the new features are more ‘I wouldn’t mind having that’ than ‘I’ve gotta have that!
If it ain’t broke, don’t fix it–that seems to be Canon’s approach to its EOS 30D, the follow-up to its perennial favorite, the EOS 20D. Aside from a few performance tweaks, the Canon EOS 30D is the same camera as its predecessor.
EOS 30D is a great camera, arguably the best mid-range DSLR on the market
Compare it to the competition and it’s clear that the 30D really can hold its own
Color is accurate, image noise very low, resolution excellent, and the camera is very responsive, both to the shutter button, and from shot to shot
The 30D’s interface is a model of elegant simplicity: Almost all of the controls that you’d use in everyday shooting are accessible via a button. Yet because Canon doubles up the functions of the camera’s buttons, the unit is not overladen with buttons and knobs.
Physically the EOS 30D is esentially a twin of the EOS 20D, the only obvious exterior difference being a larger LCD and a dedicated “print” button.
The EOS 30D Digital SLR is the much anticipated update to Canon’s popular EOS 20D. 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.
The continuous shooting mode is excellent, and now you have two speeds to choose from in case 5fps is too fast.
The Canon EOS 30D is the successor to the popular EOS 20D, aimed at the higher-end enthusiast market. When it was announced in February 2006 though, there was some surprise and disappointment to learn it used exactly the same 8.2 Megapixel sensor as its predecessor.
