Hey! I currently own a Canon EOS 90D and I'm thinking on switching to Canon EOS R6 II. Since I'll also be selling my lens, it'll be a brand new setup for me. I'm thinking on starting cheap and getting nifty fifty (50mm f/1.8) lens. I currently own a 17-50mm lens (Tamron 17-50 XR f/2.8). How would it work for me? How much of a crop I should expect? Thank you!
