Canon rf 100 500mm f 4 5 7 1l is usm vs canon 100 400mm f 5 6 8?

This site doesn't have a page for the Canon 100-400mm f/5.6-8, so I can't give you a fair side-by-side. What I can tell you is what the RF 100-500mm does. It covers 100-500mm on full frame, it's stabilised with autofocus, and it gets darker as you zoom, from f/4.5 to f/7.1. On APS-C it frames like 160-800mm. It fits a wide range of Canon RF bodies, from the Canon EOS R8 and Canon EOS R50 on APS-C to the Canon EOS R5 Mark II on full frame.

For choosing between long zooms, the Wildlife and sport guide explains how focal length and sensor size change the reach you get. The Focal length converter shows how aperture behaves across sensor sizes. Check the 100-400mm's own specs before you buy.
