Lenses are designated with lots of numbers, one primary one being the focal length. In this section Thom explores what exists, how different types of lenses are used, what's missing and what might be coming in focal lengths.

If you want to see what angle of view various different lenses are in both APS/DX and full frame/FX format, check out Nikon’s Lens Simulator.
