Can the Awesome Canon EOS R Replace Your DSLR?

We sincerely love receiving emails from our readers; especially when we feel that we've helped them and they're curious to learn more.

He's owned the Canon 5D MK 4 for years, and after reading our Canon EOS R review update, he's curious about making the move to mirrorless. But will it work for him?
