Originally posted by blwnhr The one that really annoys me is LENSE.
Lense is simply a variant of "lens." Years ago, many used the word "lense" to describe a system which contained several individual glass elements, with each of those elements called a lens. Thus, the device on the front of a camera would be called a "lense," with several of those devices called "lenses." Most filters, on the other hand, contain a single lens. The word "lense" is now mostly archaic, though many old-timers like myself still tend to use it occasionally.
