Canon rf 200 800mm f 6 3 9 is usm vs canon 100 500mm f 4 5 7 1?

The Canon RF 200-800mm f/6.3-9 IS USM reaches further, to 800mm, and it's stabilised with autofocus. It gets darker as you zoom in, though. The Canon RF 100-500mm f/4.5-7.1L IS USM stops at 500mm but is brighter at its long end, f/7.1 against f/9.

For distant birds and wildlife, I'd go with the 200-800. On an APS-C body like the Canon EOS R7, it frames like 320-1280mm on full frame, which is a lot of reach in a fairly manageable package. On full frame, the Canon EOS R6 Mark II is a sensible partner.

If you'd rather have a little more light at the long end and don't need the extra reach, the 100-500 is the better fit. Check its page for the details. For more on choosing reach, see Wildlife and sport.
