One limit of this table: it lists only Canon RF lenses that mount natively on the Canon EOS R50 — lenses fitted through an adapter are not included here. See which mounts adapt to which.
What these focal lengths actually give you on the Canon EOS R50
The Canon EOS R50 has an APS-C sensor, so it sees a 1.6× crop of what each lens projects (Canon's APS-C is 1.6×, not the 1.5× used by Sony, Nikon and Fujifilm). Every focal length below therefore frames 1.6× tighter than its marked number. That works in your favour here: the Canon RF 1200mm f/8 L IS USM reaches 1920mm of effective reach, which on a full-frame body would need a longer, heavier and far more expensive lens.
