When to use it#
At f/8, a 16 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 everything to infinity; for maximum front-to-back sharpness focus at 1.62 m and everything from 80.8 cm to infinity will be acceptably sharp.

Frequently asked questions#
What is the depth of field of a 16mm lens at f/8?
On APS-C, focused at 3 m, it is infinite (beyond the hyperfocal distance); at 1 m it is 1.98 m.
What is the hyperfocal distance for 16mm f/8?
1.62 m (5.30 ft) on APS-C. Everything from 80.8 cm to infinity is acceptably sharp.
