12mm Lenses
A 12mm lens gives an ultra-wide angle of view. It exaggerates perspective and fits a lot into the frame, which suits architecture, interiors, landscapes and astrophotography.
On APS-C a 12mm lens frames like about 18mm (Canon APS-C: 19mm) on full frame; on Micro Four Thirds it frames like 24mm.
We list 200 lenses that include 12mm: 74 primes and 126 zooms across 13 mounts, with a fastest aperture of f/2.0.
