George, I just skimmed through the article, and Richman talks about running back and forth to his computer with the card from the camera to adjust the focus, and says it took 2 hours for 2 bodies and 8 lenses. The moire discussion is earlier and has nothing to do with adjusting the system.
The moire technique for AF adjustment is considerably faster and considerably less exercise.

(yes, he bought one of each and a bunch of lenses) He includes a chart of his results with both bodies and several lenses. Not that this has anything to do with Pentax, but it was interesting to see how different the results were with the same lenses on two different bodies. This is a link to the review page. The part about lens alignment is all the way at the end. It's a long article, so if you don't care about the camera review, just scroll down. <http://www.luminous-landscape.com/reviews/cameras/nikon_d800__e_initial_impressions.shtml> gs George Sinos -------------------- [email protected] www.georgesphotos.net plus.georgesinos.com On Sun, Apr 29, 2012 at 8:18 AM, Rick Womer <[email protected]> wrote: > That's correct. > > Feeling Dave's pain in running back and forth to the computer with the SD > card to adjust focus, I will refer once again to the excellent, quick, > live-view-based AF-adjusting method using one's monitor with a target pattern > and moire: > > http://www.northlight-images.co.uk/article_pages/cameras/1ds3_af_micoadjustment.html > > > Rick > > http://photo.net/photos/RickW > > > ----- Original Message ----- > From: Paul Sorenson <[email protected]> > To: Pentax-Discuss Mail List <[email protected]> > Cc: > Sent: Sunday, April 29, 2012 9:12 AM > Subject: Re: Question regarding AF Fine adjustment K-5 > > As you go to the adjustment screen, you have a choice of selecting the > adjustment to apply to all lenses or just one.
