XSi vs. XTi vs. 40D
All crops are 150x250 pixels. The XSi at 12.2MP represents a smaller at the same pixel resolution as the 10.1MP 40D and XTi. The full-size images, which you can see by clicking on any crop, represent the same field of view regardless of the resolution.

It should be apparent that despite the XSi's 20% increase in resolution image noise is all but the same at ISO speeds to 800. At ISO 1600 the XSi does exhibit slightly more noise than either the 40D or the XTi, but the XSi is still well below the ISO 3200 noise levels of the 40D. in total, this performance is certainly good news for those considering the purchase of the XSi. Since the ISO 3200 crop of the 40D is noisier than either 1600 crop of the XSi or the XTi it appears the only reason for not including ISO 3200 in the XSi is differentiation of the lower cost XSi from the prosumer 40D. It appears ISO 3200 would be a good addition to a future update of the XSi (450D).

The last table I believe is a comparison of the XSi and the Sony A350 not:ISO Comparison - Canon XSi vs. Nikon D60
As the name of the table suggests.

The table has been corrected.viqarqadir2 - Monday, May 5, 2008 - link
The first digital rebel had a 5.3 (5.1 effective) CMOS sensor and not the 6.3 you mentioned.Roy2001 - Monday, May 5, 2008 - link
Do you have a Rebel? Stop misleading!viqarqadir2 - Tuesday, May 6, 2008 - link
Yes I do have a digital rebel. Its been put away for a while now so I seem to have forgotten the pixel count on it. It does indeed have a 6.5 Mp sensor. I dont know how I got it into my mind that it has a 5.3 MP sensor but I have believed that for years now :)Sorry about the mistake

According to Canon the original Digital Rebel had 6.3 effective megapixels (6.5 total megapixels) as detailed in our tables. These specifications are still available on their website.
