Are you crazy? My entire point of this thread is that at a given f-stop wide angles are harder to focus than telephotos ( longer lenses ). The zoom example is a near perfect PROOF that as the focal length gets longer and all else is held equal (like f-stop and lens quality ), the focussing gets easier. Or cant you make simple deductions like that. Its very scientific, and by the way, there are 35-105mm zooms, I own one, and its much easier to focus at 105mm F3.5 than it is at 35 f3.5. jco

Hmmmm, I thought the question was about 35mm lenses... or was it 105mm? Now I have to use a zoom? How about if you stick with one argument and stop changing the tests to fit the results YOU want see? You would make a horrible researcher, John, by totally disregarding the scientific method. -- Christian http://photography.skofteland.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
