Performance/Speed
In this area, the Digital Rebel XSi easily takes the cake. It can shoot 3.5 fps continuously whereas the PowerShot G9 chugs away at a much slower 1.5 fps pace. The burst speed isn’t the only area where the XSi excels: the DSLR starts up and takes its first shot faster, doesn’t have the shutter lag that the G9 has, and writes images faster and can therefore shoot continuously longer.
