When to use it#
At f/8, a 85 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 58.6 cm of sharp zone; for maximum front-to-back sharpness focus at 30.2 m and everything from 15.1 m to infinity will be acceptably sharp.
