When to use it#
At f/16, a 105 mm lens on APS-C is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get 50.8 cm of sharp zone; for maximum front-to-back sharpness focus at 34.6 m and everything from 17.3 m to infinity will be acceptably sharp.
