"on the 5D, since it’s a full frame camera, all lens mm equivelents are true, so a 28-135mm lens is a reasonably wide to intermediate telephoto. On the 7D this same lens (the kit lens, incidentally) becomes a 45-216mm, not very wide but longer on the telephoto end."

this is a bit misleading: the lens is still a 28-135mm. but used on the 7D the field of view is equivalent to a 45-216mm lens on the 5D.

Thank you very much for this. I've been pulling my hair out trying to decide which is for me, and even to just discover the full specs of each of the cameras.

Nothing to do with fat32. It is just due to the big difference in import taxation costs between stills and video cameras to EU countries. Crazy but true.
