I just upgraded from a 7D (which I still have) to a 5Diii, and it's an amazing upgrade! I'm starting to wonder if my 7D needs some service work because the difference was so dramatic. My lenses are alive, alive!! Since I am getting into portraits and other possibly paid work, I'm debating trading in the 7D for another 5Diii (the 5Diii really is amazing in IQ, focusing, even the HDR is great though not perfect). I was also thinking of trading the 7D for a 5Dii, or maybe just send in the 7D for some a tune-up (it's only got about 15000 clicks on it). I lean slightly towards the 5Dii, because that will leave some funds for another lens (maybe 16-35 or tam 24-70). Any advice? Thanks!
