I've never messed with the AF Fine Adjustment before, but I think I need to on the K-3. So those of you that have experience in this area...
First, I'm wondering if the procedure is the same on K-3 as it has been for other Pentax models? If so, I don't need to limit my Googling to the K-3. Secondly, this works with third party lenses also, right? I've got 3 Sigma EX to 2 Pentax in the AF department. Thirdly, am I correct in thinking that this is of no use on manual focus glass? Fourth, what is your procedure? I'm thinking camera should be locked down on a tripod and I'm wondering what you use for a target. I've seen scales (like a tape measure or yardstick) angled at a 45 degree angle, with a vertical target that is perpendicular to the sensor plane at the focal point. At what distance do you do the measurement? Minimum focus distance? Medium focus distance? I'm also guessing you do this with the lens wide open so as to be able to most accurately define the in-focus point. What is your procedure on zooms? I'll stop with the questions now. Any light that you can shed... thanks in advance! -- Photographers must learn not to be ashamed to have their photographs look like photographs. ~ Alfred Stieglitz -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
