On the old Canon EOS 500N, I bought a reduction for Nikon F lenses last month. I used another reduction for Pentacon Six lenses for this reduction. This allows me to use all my Nikon lenses and all P Six lenses on Canon bodies. Yes, it can’t do autofocus, it doesn’t transmit aperture values ​​for the exposure meter, which fortunately doesn’t limit me in anything. And that’s enough for my photo shoot. By buying two cheap reductions, I saved the purchase of additional lenses. Lens reductions means cost reduction 💲😉
