Summary: Love this camera. I'm an intermediate photographer, it works well for me. I bought it after reading tons and tons of reviews and I'm glad I did. It doesn't have all the bells and whistles that newer models come with, but as an introduction to DSLRs, it's a great camera for the price.
Summary: Great camera for beginners. On of the best features is the wifi. If you have a pixma printer connected to your network, you can print straight from your camera. Good pics. It is a little more on the complicated side for beginners but a good learning SLR camera for the money.
Conclusion: An excellent midrange digital SLR, the 30D has given way to its even more excellent successor, the 40D. However, it remains a great choice if you can find it at a good price. I must say that this camera is very satisfying!
Pros: Excellent low-light performance; fast and responsive; straightforward controls; nice balance of features for both experienced and rookie photographers.
Cons: Pop-up flash casts shadow with some lenses; viewfinder provides only 95 percent view; average battery life; 1.6X lens-conversion factor.
Summary: Buy the 40D if you want a better all around camera. I like it better than the 5D.
Pros: I have used the 30D for over a year now and have gotten some great pics from it. L glass is of course the best choice. Camera has worked flawlessly. I just bought a 40D and would suggest that if you can justifie the added cost that you buy it instead. Better all the way around.
Summary: As a long time Canon film SLR I was slow to pick up a digital camera. In fact my wife was first. She bought a Canon Elph SD700 IS for a trip. By the second day we were fighting over it. I since have used it a lot but find its button controls just too small.
Summary: The EOS 30D isn't much of an upgrade from the 20D, with a few new features such as true spot metering. If you've already got a 20D, you might as well sit tight and wait for the next generation. (The EOS 5D isn't really an upgrade option for 20D owners if they own many EF-S lenses.
Summary: Camera has only around 8MP, but still is capable of good pictures. While it doesn't compare to newer models like the 60D (which I now own as well), it's great for the price conscious buyer and can definitely get the job done.
