70-200mm F2.8 lenses generally represents one of the most used focal range&aperture combination in a photographers arsenal but due to their fast aperture and wide converage, they are large and heavy. Below you can find the size comparison of 70-200mm f2.8 lenses for mirrorless mounts from the Big Four: Nikon Nikkor Z 70-200 F2.8 VR S vs Panasonic S Pro 70-200 F2.8 O.I.S. vs Sony FE 70-200mm F2.8 GM OSS II vs Canon RF 70-200mm F2.8L IS USM.
Canon is by far the most compact of these four thanks to its Rotary (Extending) zoom design while all the other lenses are Internal Zoom designs. We are not a huge fan of Extendin zom designs especially for more pro-level lenses but the size advantage of the Canon RF 70-200mm is so big compared to others that it becomes a very attractive option for many.
Tallest: Nikkor Z 70-200 f2.8 at 220mm
Heaviest: Panasonic S 70-200 f2.8 at 1570g
Shortest: Canon RF 70-200 f2.8 at 146mm
Lightest: Sony FE 70-200 f2.8 at 1045g
