When to use it#
At f/8, a 105 mm lens on full frame is a natural choice for landscapes and architecture where front-to-back sharpness matters. Focused at 3 m you get 38.0 cm of sharp zone; for maximum front-to-back sharpness focus at 46.0 m and everything from 23.0 m to infinity will be acceptably sharp.
