EF/EFs/cropfactor/fov brain explosion !!!

Here's one I made ages ago, but it's nice to think there might still be some people who would benefit from it.

The left hand side of this is the view through an EF lens. The right hand side is the same view through an EF-S lens with the same focal length. You can see that the choice of EF or EF-S lens makes no difference to what you get in the photo on a 1.6x crop camera.
