Ehh... Although the glass is important it also depends on what you're shooting! ~> I would hate to go to shoot a professional Sporting Event w/ a slow camera!

Example: Rebel = 3 frames a second ~> The Rebel cant write them to the CF card that quick enough so after about 30 jpegs/ raw images, the LCD Screen will read Busy... =

You need a Nice Body and Nice Glass! ~> Hence why most of us are broke as a joke .
