By default, this 200mm lens has a minimum focus distance of 2.62 ft or 0.8 meters. But that can be extended out to 800mm for much clearer long-distance shots with a minimum distance of 10.83 ft or 3.3 meters. Of course, that’s if you don’t use an extender. Sticking an Extender RF2x on top of a Canon RF200-800mm doubles its focal length even further to 1600mm, potentially making it one of the best super-telephoto lenses around. That’s partially thanks to Canon’s Optical Image Stabilization (OIS), which Canon claims provides “enhanced shake reduction for up to 5.5 stops”. When paired with Coordinated IS on the Canon EOS R-Series cameras, these benefits combine for “reliable handheld performance and clearer detail in low-light situations, without having to increase the ISO or decrease the shutter speed.”
Canon’s RF200-800mm F6.3-9 IS USM lens features a number of weather-proofing features which blend right into its stylish black-and-white matte design. For instance, its white paint is actually meant to work as a countermeasure against excessive heat when exposed to direct sunlight for long periods of time, as would be the case when capturing sports footage or when shooting wildlife in an area with a hot climate. The lens mount, focus/control ring, lens function buttons, and other interface pieces are rated for dust-proofing as well. Carrying it around should be a breeze; this lens only weighs 0.55 lbs, making it lightweight compared to other telephoto lenses — which usually weigh somewhere in the 1-3 lb range.
So far, reviews of the RF200-800mm F6.3-9 IS USM skew overwhelmingly positive.
