Overview

The Canon RF 800mm F5.6L IS USM offers exceptional reach and sharpness with beautiful background separation, aided by 4.5-stop stabilization that enables handheld use for short periods. It inherits the optical design of the RF 400mm F2.8L with a rear magnifying system, including a UD element. Build quality is outstanding, but the lens is large and heavy at 6.9 pounds, best suited for stationary use or short hikes. Its $13,000 price targets professionals; hobbyists may find it prohibitive.
