I'm in the market for some new gear. I've been using a 6D for a few years now. The image quality is fantastic but the focusing system is potato and I find myself needing better. I do have a 7D which I bought as a backup to my 6D. The 7D was great and I ended up favoring it over the 6D much of the time but unfortunately something went wrong in the electronics and the camera is dead. I photograph people, portraits, events, and sports for work. Nature, wildlife and astrophotography as a hobby. There are definitely times one camera would work better than the other or times when it would just come in handy to have two cameras at hand. My options are: 1. Sell my 6D and get a 5D Mark III. I really like the idea of a 5D Mark III. It would do everything I need and I would have a camera that focuses. The downside is I wouldn't have a backup or a second body. 2. Keep the 6D and get a 7D Mark II. I would still use the 6D in 6D situations and I'd have the 7D Mark II for backup and 7D Mark II situations. I also like the video capabilities of the 7D Mark II. 3. Get another old 7D and maybe some new glass. What would you folks do?
