Canon RF 100-500mm F4.5-7.1 L IS USM

Averaged from + undefined
The verdict

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.
