When to use it#
At f/11, a 28 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 16.4 m of sharp zone; for maximum front-to-back sharpness focus at 3.59 m and everything from 1.80 m to infinity will be acceptably sharp.
