When to use it#
At f/16, a 135 mm lens on full frame is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get 45.5 cm of sharp zone; for maximum front-to-back sharpness focus at 38.1 m and everything from 19.1 m to infinity will be acceptably sharp.
