[edit] Explanation

I'm not following the article. I think I understand what the rack focus technique is, described in the first sentence. But what does that have to do with a non-reflex lens viewfinder arrangement? What does the last sentence mean?:

rack focus the camera by looking through the viewfinder then sliding the camera over so that the shot would be in focus.

Is it suggesting the camera split apart so the viewfinder could be in the focal frame? Or is it merely that the viewfinder showed the correct focus, but was significantly off-axis? Neither is obvious how it would connect to the focusing effect. —EncMstr 04:42, 13 March 2007 (UTC)
