When to use it#
At f/16, a 28 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 31.7 m of sharp zone; for maximum front-to-back sharpness focus at 3.29 m and everything from 1.65 m to infinity will be acceptably sharp.
