With its long-running Rebel series of consumer DSLRs, Canon has earned a reputation for cranking out new models on a consistent timetable that are rarely revolutionary, and yet often set the pace for the entry-level market nonetheless.
There is some heavily hyped technology – including live view and a newly developed 12.2 megapixel CMOS sensor – in the new Canon Rebel XSi, but for the most part, the new Rebel looks to be yet again an incremental upgrade to the XTi platform it supplants.
Sitting somewhere between the basic "true entry-level" models and advanced-amateur cameras like Canon's own Canon EOS Rebel Xsi, the XSi continues to push the resolution envelope, reprises the XTi's well-regarded auto focus system, and at once offers more custom functions and advanced control for the serious photographer and a fairly mature live view implementation aimed to entice shooters to step up from compact point-and-shoots.
As one of the undisputed market leaders, expectations are always high for Canon, but early murmurs significant improvements to the formula of Rebelde, in addition to performance-class sensor, which is served in the same list price that previous generation XTi XSi seemed more promising as a carrier of new consumer digital SLR quality standard in the world.
The Canon Rebel XSi (a.k.a. the Canon EOS 450D) is Canon's latest mass-consumer DSLR, moving into the company's lineup one step above the current Rebel XTi. Continuing in the tradition of the Digital Rebel cameras, the XSi features a proprietary CMOS sensor with an effective 12.2 megapixels of resolution, making it Canon's most high-res entry-level offering to date. The XTi's nine-point auto focus system returns with some slight tweaks, and the new Rebel gets an enormous 3-inch LCD.
LCD is particularly significant because the new XSi camera Unknown is also the first Canon entry-level sport of Live View system that allows the screens used in the composition of. The XSi's live view implementation moves beyond the basic with the addition of a contrast-detection AF mode that allows the camera to auto focus without interrupting the on-screen preview to do so – a feat not possible in the first generation of live view DSLRs.
