Hi Joseph, glad to help. I must admit I only read the parts of manuals I need better understanding of, I just remember reading that in the K10D manual some years ago. When I got the K20D I think the only thing I read was about extended sensitivety and AF adjustment. I've always found Pentax SLR/DSLR's very intuitive to use.

That's why I was under the impression that some DA lenses did not have manual override! 99% of the time I'm in 'C' focus or manual focus. When I am in 'S' focus mode, I'm trusting the AF to get it right on a mostly stable subject. Another disadvantage I just discovered was not being able to stand steadily. Just shot a series of close-ups of equipment for eBay, handheld, from a foot to three feet away with the SMC-A 50 mm macro. I could not easily focus consistently, and was rocking back and forth in an attempt to be still and shoot. Even with a monopod. So my solution was to focus once, and wait until good focus appeared to be approaching once more as I rocked, and shoot. My own predictive autofocus with a manual focus lens. Thank you for reading the manual for me. I never do get more than a page or two at a time read in any manual before I'm bored or confused. This list allows me to find out what the features are on my equipment ... :-) P.S. Using a tripod was impossible in the space I had to work. It would have slowed things considerably in composing and shooting dozens and dozens of items of different sizes. I also found many had to be reshot because they had a dog hair or two attached to the gear. :-) On Apr 14, 2009, at 01:59 , John Whittingham wrote: > All DA lenses have Quick-shift focusing (manual overide) IIRC the > manual states it works in AF-S (Single) but not AF-C, my camera is > usually set to AF-C for the majority of the time I use it. > > Regards, > > John > ________________________________________ > From: pdml-boun...@pdml.net [pdml-boun...@pdml.net] On Behalf Of > Joseph McAllister [pentax...@mac.com] > Sent: 13 April 2009 23:00 > To: Pentax-Discuss Mail List > Subject: Re: Difference between 16-45 and 17-70 > > I probably shot a few test shots after it was unpacked, but I use the > DA*16-50 on a regular basis for indoor and lower light shots. > > I don't think any of the DA lenses that are shaft driven only have > focus override.
