100mm Lenses
A 100mm lens gives a short telephoto field of view. It flatters faces and separates subjects from backgrounds, making it a classic portrait length.
On APS-C a 100mm lens frames like about 150mm (Canon APS-C: 160mm) on full frame; on Micro Four Thirds it frames like 200mm.
We list 980 lenses that include 100mm: 92 primes and 888 zooms across 19 mounts, with a fastest aperture of f/1.8.
