Although most of my recent year images were captured using medium-format systems, I do use 35mm cameras from time to time, particularly when the reach of a telephoto lens (e.g., 100-400mm) is called for, or when shooting in inclement weather.
Most of my old images were also taken with 35mm cameras.
I have used Canon 5DSR, Canon 5D Mark III, Canon 5D Mark II, Nikon D810, Sony A7R2, and Sony A7R3, etc. I have used all sorts of lenses on each system. Canon EF 11-24mm f/4 L, Canon TSE-17 mm f/4 L, Canon TSE-24mm f/3.5L II, and Canon EF 100-400m f4.5 II are still some of my favorite lenses.
I will not spend much time discussing these 35mm systems, as one can find millions of articles about them. However if you have questions feel free to ask me.
