After 70โ200, I wanted something more telephoto. The choice of RF lenses at the end of 2022 is not so great - RF 600, RF 800 or RF 100-500. But I wanted the lens to focus from 90 cm, and not from a few meters, so I settled on RF 100-500. Of course, I compared it with the EF 100-400, primarily in terms of aperture ratio. So, characteristics 100-400 in parentheses, RF 100-500 in square brackets.
