Canon RF 100-500mm f/4.5-7.1 L IS USM
The RF 100-500mm f/4.5-7.1 L IS USM is a pro-tier (69) full-frame RF telephoto, the flagship wildlife and sports zoom delivering 500mm reach in a hand-holdable 1.4kg body with a 77mm thread. It pairs well with Canon's RF 1.4x and 2x extenders for birders. The f/7.1 maximum at 500mm limits low-light telephoto use, and it's a premium-priced lens, not a budget-kit pick.
