Last July, I bought a used 7D (Mark I) because I wanted to have a second camera setup for shooting the solar eclipse. Soon after that, the 7D became my "main" body. Even though my (previously main) 70D had higher resolution and the flippy screen (which I used a lot for holding up and shooting over people and obstacles), the 7D fit better in my hand and felt more solid, and I liked the joystick controller and the AF point expansion mode.
This past January, I sold the 70D and bought a used 7D Mark II. I kept the 7D, thinking it's a great camera to keep as second body. But the truth is I haven't used it at all since getting the 7Dii. I don't typically use two bodies (total solar eclipses notwithstanding), and I'm thinking now that I'd like something smaller and lighter as a second body for business travel (or hiking/biking), when I want to bring a DSLR but I don't anticipate needing the higher performance (and size/weight) of the 7Dii.
So I'm at a bit of an impasse. I think the 7D is still a great camera despite its age, and I don't want to get rid of it, but I never use it. The rational side of me says to sell it and put the proceeds toward something smaller, but another side of me is saying to hang onto it in any event.
Any thoughts and insights from the POTN crew are greatly appreciated!
