I know, search... but I did and with the 5Dii showing up so much, I haven't found a ton of info.
I'm flirting with the idea of selling off my 40D+grip+Tamron 17-50 to come close to having the money for a used 5D.
I shoot all kinds of stuff. I find myself shooting sports once in a while where the 40D would clearly be better, but my major areas are art, portraiture, and just family stuff for fun (my daughter is starting to stand, will be walking within a couple of months). I currently find myself shooting my film cameras often for that "look" which I think has a lot to do with the 35mm frame and I am expecting from a 5D.
I realize the 5D will be better for portraiture, or if I shoot any more weddings, and the added depth of field is nice for art photography. I have a pretty good grip on the difference in the fps and AF, and think I am totally fine with that for what gains in high ISO and shallower depth of field. But in terms of the fact that the 5D is an older generation camera, what will I loose from the 40D. I think the 5D doesn't have the dust reduction sensor, doesn't show the ISO in the VF, has the older menu system (maybe?) and a smaller screen.
Is there anything else I am missing. What is the auto ISO range, I use that a lot on the 40D? Is the weather sealing better or worse compared to the 40D?
