When to use it#
At f/11, 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 6.16 m of sharp zone; for maximum front-to-back sharpness focus at 4.78 m and everything from 2.39 m to infinity will be acceptably sharp.
