So over the Thanksgiving weekend, I finally gathered the nerve to just let go of my 5D3 as I was offered a fair price for it. That, in conjunction with the deal for the 6D at $1400 pushed me into pulling the trigger on the swap out. Done and done.
Some things I'm struggling with, some not so much. Either way, I think the decision was the right one for me (for now).
Wondering if anyone else has given the same move some thought.
I haven't done exactly what you have done BUT I had the chance to shoot with a 5D3 for the day and now that I have, I won't buy one. I will keep my 7D.
The 5D3 is a great camera but not worth (at least to me) the $3400 price tag. After reading people's thoughts and reviews I was expecting a powerhouse of a camera, and it really wasn't. I just couldn't justify spending the money on it to upgrade. The 7D is a VERY fast camera and very hard to beat in that department. I shot BIF (birds, raptors exactly, in flight) with the 5D3 and got 10 times more blurry bird shots than I did with my 7D! (Yes I KNOW how to set up my camera for birds in flight, I am NOT new to this! Please don't waste your time telling me how I didn't know what I was doing... I always select the center point on AF and use AI Servo...) I was also using my own EF 70-300L on the 5D3. That lens is lighting fast on AF, so I know the fault wasn't with the lens.
I know a few people will say that I didn't give the 5D3 a chance to give it an honest opinion. Well, let me say this, I had (on loan) the 5D3 for a day and took well over 1000 photos AND was shooting with friends who OWNED the 5D3 and I was asking questions and they were gladly giving me pointers. By the time the day was over, I was so frustrated after shooting with it for a day and getting missed shot after missed shot. In contrast, when I upgraded from my 40D to my 7D, the transition was almost seamless. I had the 7D mostly figured out in just a few shots and was very happy with my decision. It was so much faster (in AF and fps) than my 40D that I was sorry I hadn't upgraded sooner! I learn more and more about it the more I shoot. Honestly? I had really been wanting a 5D3 so I know I was excited to give it a try. It just did not deliver enough goods to make me want to give up my 7D.
A few of my photography friends who upgraded to the 5D3 say that most of the time 5D2 did just as good of a job and in some cases the 5D2 was better.
I spoke with a good photography friend of mine after I used the 5D3 and told him that I still preferred my 7D over it. Before I tell you what he said, let me say that my friend Kenny is a published and very respected photographer and has owned and/or shot with just about every camera body Canon has ever made, including the 1DX and the 5D3, for starters. He has many friends at Canon and I have learned to respect his words of wisdom. He said to me, "Well, what did you expect? The 7D was designed for speed and the 5D3 was designed mainly for studio work and weddings like the 5D2 was. The 5D3 is a little faster and has better video than the 5D2 but it wasn't designed around speed. You shoot wildlife so the 7D is going to be perfect for that at a fraction of the cost!"
I couldn't argue with him...
The 5D3 may be a very fast full frame, but not as fast as the 7D. But again, that is my opinion. I used to own the 5D2 and let the ex-wife have it in the divorce, I wasn't super impressed with it either, outside of it's image quality. I shoot wildlife and the 7D is perfect for that.
So, I respect your decision to sell the 5D3 and get the 6D. I probably would have done the same.
