Talk:Exit pupil
From Wikipedia, the free encyclopedia
[edit] Small update
Formatted the article and added a small section on relative brightness. This article may need a picture showing the lens on a camera... I would add one except I need my camera to photograph the lens and the lens is firmly attached to the camera... I tried a mirror but I'm just not steady enough. Also an equation relating the f-number to the focal length and the objective lens to the magnification would be a good addition except I'm not sure of the standard symbols for each. -- Bob-505 00:22, 8 June 2006 (UTC)
- I took out the bit on relative brightness, as it was manifestly untrue for camera lenses, and was covered sort of already in the section on direct-observation instruments. I'm not sure what you have in mind with camera lenses; the exit pupil size and position are not functions of focal length and f-number, but more complicated. Dicklyon 07:20, 1 August 2006 (UTC)
