When to use it#
At f/8, a 600 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 0.6 cm of sharp zone; for maximum front-to-back sharpness focus at 2.3 km and everything from 1.1 km to infinity will be acceptably sharp.
