I think this better illustrates the size difference between a rebel and the g1x than some of the others I've seen done from the front. You can switch lenses and bodies as you see fit. I don't think there is a way to shot the g1x with the lens extended, but you can still see it's going to be much smaller than any dslr with a zoom.
