The 100-500mm L is Canon's best all-around wildlife zoom for RF. 500mm of reach in a 1.53 kg lens is genuinely impressive — most photographers can handhold it all day. The L-series optics deliver pro-grade image quality across the range, and extender compatibility extends usable reach to 1000mm. The catch is price — at $2,900 it's roughly half the cost of the RF 70-200mm F2.8 + extender combo, but still a premium investment.
Strengths
- +100-500mm range with L-series optics — best wildlife all-rounder for Canon RF
- +1.53 kg weight is unusually light for a 500mm-reach L lens — handholdable for hours

- +Compatible with Canon Extender RF 1.4x and RF 2x for 700mm or 1000mm reach
- +The-Digital-Picture and Nature TTL consistently rank it Canon's best wildlife zoom
Watch-outs
- −Most expensive pick in this round-up at $2,900
- −Variable aperture (f/4.5 at 100mm to f/7.1 at 500mm) — slower than the RF 70-200mm f/2.8
- −Extenders can't be used simultaneously — pick one
- −Front element rotates during zooming — polarizer use is fiddly
