Talk:Focal ratio

I'm not sure what the intent was here. This article is completely redundant with the preexisting f-number. The existence of multiple names for the same thing does not justify a second article. Wikipedia handles multiple names with redirects. If there was content here that was missing at f-number, it should be added there, not here.--Srleffler 19:51, 20 October 2006 (UTC)
