You are confusing depth of field with accurate focus. If you dont care about the depth of field and all you care about is if your subject falls SOMEWHERE in the depth of field you might have a point, but most photographer focus on a specific distance even with high depth of field condtions to control the foreground and background DOF zones around the subject. I know I do, especially when wide f-stops/shallow DOF conditions exist.
Ever used a 35mm F2 at F2? I have, and you definately need to focus it. Your longest glass might be your most difficult to focus but if you have wides at the same speed they would be even harder. What speed is you longest manual glass? Mine is a 1000mm/F8 and its easier to focus than a say a 20mm F8 would be, I can tell you that. As for armchair comment, I have been using SLRS to take photos for over 30 years so your comments are without merit. I dont just guess about these things, they are based on both long experience with many many cameras and lenses of all types and all the optical theory I have learned over the years. Are you saying you dont find zooms eaeier to focus more accurately at the long end, too? Because if you are, I cant believe it, as I have never found that to not be the case with any zoom I have ever used. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Toine Sent: Saturday, November 11, 2006 3:55 AM To: Pentax-Discuss Mail List Subject: Re: Using a Super Tak w/ istDS- A challange to the list? I do. In fact I don't need to focus at all using wide lenses. And my longest manual glass is the most difficult to focus. Are you sure you're not an arm chair photographer (nothing wrong with that). I can't remember any pictures. On 11/10/06, J. C.
