IMHO extended DOF of wide angles also does have something common with this technique (and rangefinders)... If the lens is wide enough you don't have to focus at all. It would be a lot harder to focus, say, 135mm lens that way. Peter - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
