When looking at improvements, the Canon Rebel XSi has numerous advantages over the previous models in the Rebel camera series.
The XSi is sporting a new 12.2 MP CMOS sensor, which is a nice improvement over the XTi’s 10.1 MP sensor. For an entry level, dSLR camera, the megapixels are reaching nice sizes for poster size printing.
Canon has also sped up the camera’s fps (frames per second) from 3.0 to 3.5, which makes a big difference when shooting in burst mode. For beginning sports photographers on a budget, this is a great improvement.
One of the most noticeable differences is the gorgeous 3.0” LCD display, an upgrade as well. This was an upgrade that some had hoped for with the XTi, but were disappointed. With the XSi, this big display, previously only found on the higher end models, works great with the new Live View shooting, which will be discussed below.
Another improvement over previous models includes some subtle changes in the viewfinder. Despite the few who will use the Live View for most shooting, most of us will prefer to have the control over the picture that the viewfinder affords us. The new viewfinder presents the photos in a brighter way, and it also displays all of the exposure information. This was something that was lacking in the previous models and was, quite frankly, irritating when shooting in fast paced environments.
