Oh wise and all knowing canon rumors community, I require your insights.
Here's the deal. I have a 5d2, and a 5d3. My longest lens is a 70-200 2.8 IS L. I make 99% of my money from photographing weddings.
I am thinking about trading my 5d2 for a 7d with some cash, then using that cash towards the mighty Canon 100-400 IS L lens. I'm wanting to try doing some sports and wildlife and whatnot. I don't know if I'll be able to profit from these different endeavors, but I'm going to try.
The reason I think I might be crazy for doing this is because im not sure how I'll like the 7D's image quality compared to my beloved 5d3. Is the extra "reach" the crop gives you worth the lower IQ? I know the 100-400 is not a fast lens, but will I be frustrated with it, especially if its on the 7d and I can't push my iso as high?
A friend and colleague of mine had a 7d and got rid of it because he didn't like its IQ compared to the 5d2. That kinda worries me. Plus, having two FF cameras is more beneficial to me for wedding work than a crop would be. But adding that crop sensor gives me more, and different, capabilities. I guess its all about trade offs.
So, people, what do you think? Will I hate the 7d after using the 5d3? Any tips on making money with shooting sports/wildlife? Am I crazy for thinking about doing this? As far as shooting weddings, out of the ~1000 photos I take, about 50 are on the 5d2 for wide angles during the ceremony with the other ~950 taken on my 5d3. So I don't know if I'll really miss the 5d2 that much...
Sorry for writing so much, but I wanted you guys to be able to give me some well informed advice and opinions. You guys know what you are talking about, so I shall defer to your experience! Thanks!
