Hello guys,

sorry, I can't see any posts here.
Currently, I have a basic EOS 600D DSRL cameras, I bought it four years ago, now the lens (kit lens) doesn't function good, I mean it can't focus correctly. I had disassembled the lens before, spent almost whole night to reassemble it.

I am thinking to upgrade my photography gear, you know, maybe I should purchase the EOS 7D or EOS 70D. Nowadays, these cameras are offering discount. My question is how to choose between EOS 7D and EOS 70D.

By the way, I use the camera to shoot products photos, I had setup a small but effective light room for shooting purpose.
