What I like about the Canon XSi/450D

• Outstanding image quality, beautiful colors.
• Impressive exposure metering.
• Fast and responsive.
• Excellent high ISO performance; eye-popping for those of us who only used compact digital cameras before buying the XSi.
• Bright viewfinder and large three-inch LCD. LCD information is easy to read except in very bright light.
• Proximity sensor - automatically shuts off the LCD when the camera is raised to your eye
• Almost all camera features a photographer needs to access while taking photos have a dedicated button; most buttons are well placed.
• Well-thought out menu system.
• Image stabilized kit lens produces images that are much better than expected, especially considering the low price (about $100.00 U.S. when purchased with the body). The reasonably priced Canon 55-250mm IS lens is also a winner.
• Good ergonomics
• Lightweight

What I dislike about the Canon XSi/450D

• At the time of purchase, it was expensive compared to other entry level DSLRs (with the introduction of the XS/1000D after the XSi/450D, the XSi is no longer considered entry level).
• Learning how to get correct flash exposure can be challenging in Creative Zone.
• Flash needs to be raised for auto focus assist.
• ISO button a bit awkward to access without taking your eye away from  the viewfinder.
• Live View primarily useful only for shots using a camera support.
• LCD monitor should come with an anti-glare coating.
• Wish the camera was even lighter.
• Price of a Canon spare battery is expensive.
