Talk:Focal Length – Wikipedia, The Free Encyclopedia
The field of view for a given focal length can vary a bit, between rectilinear and fisheye lenses for example; focal length determines the magnification of If you contrive a lens with the entrance pupil in a different place along the optical axis, then an object point some sufficiently small angle … Read Article
