Canon RF 200-800mm F6.3-9 IS USM

Averaged from + undefined
The verdict

The 200-800mm is Canon's wildlife and aviation reach specialist. 800mm of native reach handles birds in flight and distant subjects that the RF 100-500mm L can't quite touch — and at $1,900 it's $1,000 cheaper. The catch is the slow f/6.3-9 aperture, which means you'll either shoot in good light or push ISO meaningfully. For dedicated birders and aviation shooters who don't need an L-series build, this is the better-value reach tool.

How it compares

Longest native zoom reach in Canon's RF lineup. Cheaper than the RF 100-500mm L but slower aperture and not L-series build. Replaces the need for the fixed RF 600mm/800mm f/11 lenses for users who want zoom flexibility.
