When to use it#
At f/11, a 85 mm lens on Micro Four Thirds is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get 40.1 cm of sharp zone; for maximum front-to-back sharpness focus at 43.9 m and everything from 21.9 m to infinity will be acceptably sharp.
