When to use it#
At f/11, 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 34.8 cm of sharp zone; for maximum front-to-back sharpness focus at 50.2 m and everything from 25.1 m to infinity will be acceptably sharp.
