I have an XTi and a 5D. First off there is nothing wrong with my XTi. I just did an extensive series of pictures with it involving the hatching, nurturing and flying of two doves at close range with the XTi and a Canon 100-400L where I left the camera on a tripod in the same concealed location for almost a month. The pictures are really good. I know nothing about the 7D. What I do know is the 5D is very good in low light high ISO situations where I do a lot of photograply. I took some pictures today in bright light and marvelled at how easy it was compared to shooting in badly lit swimming arenas for instance. What I especially like about the 5D is that my 17-40 is truly 17-40 and the full frame I think produces better pictures like landscapes than a 1.6 crop but only so's you'd notice with quite large blow-ups. Just my opinion. I don't want to start an argument because I truly believe that you can get great pictures from either the 7D or the 5D as I believe that really good photography is the product of the photographer rather than the equipment. I think, using the proper lenses for each camera, that you could not tell the difference in prints from the two up to 18x24 or even larger. The 5D may be better on really large pictures. The 5D Mark I view screen is small and is difficult to view in bright light. It has but basic features compared to the 7D. When I shoot swimming in really bad light I drag the 5D along because I get usable, printable pictures at ISO 3200 when all else fails. Unless you can view 100 per cent crop printed pictures it would be hard to discern differences between the two cameras IMO.
