When to use it#
At f/8, a 135 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 15.1 cm of sharp zone; for maximum front-to-back sharpness focus at 114 m and everything from 57.0 m to infinity will be acceptably sharp.
