When to use it#
At f/11, a 300 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 5.9 cm of sharp zone; for maximum front-to-back sharpness focus at 273 m and everything from 137 m to infinity will be acceptably sharp.
