I am looking to buy a digital SLR camera. I am mainly looking at either the Minolta Maxxum 7D or Canon Digital Rebel XT. I have seen/used the 7D which is very nice camera but I don't see where the added features are to make it cost 2X the Rebel. (base only) In fact the Rebel is 8MP and the 7D is only 6MP. Features-wise they similar to have similar settings/specs. Lenses don't concern me much because I will probably get Tamron lenses anyway. Anyone have experiences with either of these cameras? Anyone have any problems with the cameras and a Mac?
