Better quantified this time. Yesterday I took stance on a bridge above a highway, and photographed large trucks coming towards me. The speed limit at this place is 100 km/h, and on top of a gentle slope. I shot series of each truck, and have tallied the percentage of out-of-focus shots from each

Good to know. It's what I suspected based on use, but it's nice to know that my suspicions aren't just wishful thinking. Thanks for taking the time to test. Paul On Jul 18, 2009, at 7:09 AM, AlunFoto wrote: Better quantified this time. Yesterday I took stance on a bridge above a highway,

The test having been done hand held, might one factor have been the K-7's claim of improved SR.(?) Jack --- On Sat, 7/18/09, paul stenquist pnstenqu...@comcast.net wrote: From: paul stenquist pnstenqu...@comcast.net Subject: Re: More K-7 AF observations To: Pentax-Discuss Mail List pdml

I always pan with SR on. In fact, I shoot off a tripod with SR on. Doesn't make any difference IMO. In fact, I didn't see anything in the K7 manual about turning it off for tripod shooting, although the K20D did suggest that it SR be switched off. Of course I've only skimmed the K7 manual.

Just don't read Ricewhine's measurbator blog on the K7's autofocus tracking. It will either shake your confidence or infuriate you. I found it by accident, and wish I hadn't clicked on the link. Not because I much care what he thinks, but I don't want to up his Google rating. He's another
