Huh? I never specifically stated primes or zooms because it doesnt matter, they both have the same characteristics, the DOF is the same on a 35mm prime as it is on a 35mm end of a zoom.
I later stated his testing method was not as good as using a zoom because you cant make a quick comparison and secondly, as everyone already knows, zooms prove my point, they are easier to focus on the long end on every zoom lens I have ever encountered. It's not true only for zooms though, its true for primes too because the difference is due to DOF which is the same for primes and zooms. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Savage Sent: Saturday, November 11, 2006 5:11 PM To: Pentax-Discuss Mail List Subject: Re: Using a Super Tak w/ istDS- A challange to the list? Yeah he did. You asked: "OK, I challenge the entire list on the matter. Does anyone here actually find or believe that wider lenses are just as easy to focus as 3X longer lenses at the same fstop?" and then you said: "Simple proof is with zooms, ..." Bill took up your "challenge" & went for the slightly more difficult "proof" by testing using primes. He said he found no difference between focusing a wide or long lens.
