Here’s a diagram created by Reddit user GeneralSarsby that shows the effective field of view of lenses of various focal lengths when used on a 1.6x crop factor sensor. You can also download the source svg if you want to edit or build upon it.

Here’s a neat image showing the different field of views offered by focal lengths ranging from 16mm to 200mm. It’s not simply lines overlaid on a single photo — the different focal lengths were actually used to capture what the scenes looks like through the lenses.
Vimeo recently partnered up with photographer Vincent LaForet for a new educational series called Behind the Glass. If you’re just getting into photography, the videos are great primers on the subject of camera lenses.
