When to use it#
At f/16, a 50 mm lens on APS-C is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get 2.64 m of sharp zone; for maximum front-to-back sharpness focus at 7.86 m and everything from 3.93 m to infinity will be acceptably sharp.
