Pros Realibility! Technology! Simplicity! New Battery! SD storage! EOS family!
Cons looks complicated to new users.
Summary I love this camera! Highly recommended to new users!
Pros Live View 3 inch screen, image stabilizer lens, automatic and scene modes as well as full manual controls, fast performance, excellent photo quality, good exposure controls and manual exposure BULB setting, easy to use for an SLR, 12MP, good battery.
Cons There are no real cons or complaints other than I wish I was able to save my own multiple personalized settings profiles (eg. specific favorite settings for night photography that I can save and come back to later) but that's not a big deal.
Summary The Rebel XSi (EOS 450D) is a great DSLR camera, perfect for beginners and pros. The image quality is excellent and boasts great performance. I love the large 3 inch screen and it is great that it has Live View, although I don't use that feature much. I like that the camera is easy to get into as a beginner and you can gradually get deeper into the settings and manual adjustments. There are the auto and scene mode options, as well as the full manual controls. The My Menu feature is also handy. The camera is comfortable to hold and overall a nice purchase.
Pros Superb image quality at ISO 1600. Long battery life. LCD size.
Cons Plastic body. Slightly uncomfortable grip.
Summary My XSi is only a few days old, so I haven't had a chance to put it through it's paces. I have the original Digital Rebel and the Sony F717 for 5 years, but I have been using my friend's XTi for the pass year. With the few shots I have taken with the XSi I am already impressed with the image quality at all settings. I had no problem navigating my way around the buttons and menu right out of the box and the IS feature on the lens is a plus. I am dying to try it with the 55-250mm EFS IS lens.
Pros easy to use, solid body
Cons only goes up to iso1600
Summary this was my first digital slr. came down to either the canon 450d xsi and the nikon d80... it seems there are nikon people and there are canon people, i was always a minolta guy, so when it came time to buying my first dslr, i did a lot of research. there are pros and cons to both the canon and the nikon. my brother is a canon guy and my sister is a nikon girl, they both presented their case and in the end i agreed with my brother. a few of his arguements stuck with me, one was that the canon is able to use nikon lenses while the nikon cant use canon lenses. second the canon is 2 mega pixels more. third, while you're able to take amazing pictures with both cameras, both are entry level dslr, neither one is going to make you a professional photographer. that being said, the first picture i took with my new canon 450d xsi is probably the most beautiful picture i've ever taken. the colors and shadows are so vibrant and the detail is sooo incredibly sharp. i cant say enough good things about it.
Pros Very light and compact for an SLR
Cons Focusing with Live View can be a pain in the neck
Summary This is my 3rd.DSLR, first one being Nikon D200, then Canon 350D and now 450D (Xsi in USA). Vast improvement over the previous 350D model. Kit lens doesn't look cheapy anymore, decent engineering and good looks with a bonus of Image Stablizing system. I use kit lens along with EF 28 -135 IS USM lens. Excellent resolution and sharpness. No wonder it's selling like hot cakes here in Thailand!
