This is very KOOL I must say. If Pentax can make this into a PRO feature in their K10D instead of a secret feature, then it would have been even better!

[KHEXT]

IMHO Pentax went way wrong with this feature. Instead they should allow people freely adjust it and in additional keep in camera light_type/lens/AF_parametrs reference table. Thus they could stomp to death any competition AF system!

From a user point of view such a feature is great. It would even be better if it could, as you say, store the values per lens. But from a commercial point view, I am not sure the general public would be happy with a camera where the user can parameter the AF.

I am not sure if reviewers will give good reviews to a camera where the user has to calibrate the AF himself. This is a setting which one should expect from the manufacturer.

For beginner or amatuer camera (K100D), there should not have such feature available to users.

For K10D as a semi-pro or professional series DSLR, I think this extra feature would be a plus

Just mention to you that Pentax compatible with very old lenses when there was no such thing as "electronic lens calibration". So I recon for Pentax such feature will be great. And also I am sure that it will be no problem with new-coming USM lenses in AF area.

I shouldn't be too sure. Today I calibrated my K100D for the DA12-24mm and now it focuses like magic:-)

Completely agree. Anyway if implemented like you have described, with some tech explain about why this is needed, it would be very much appreciated in higher level photographers.

The fact is that Pentax have to be able to sell it as a feature and not as a bug This is marketing stuff

You got the hack for the K100D?

Ok...I just saw the new link to the other hacks...

Well, I wouldn't call it a hack. It is no more than a hidden option which you make visible in the Debug Mode.

Very dangerous, just tried it and exiting is very convoluted. I had to do the Fn Fn...etc. manipulation very quickly and finally got out.  I re-did my firmware update just to make sure.

I can confirm that both of my K10D's , one more than another have front focus issues.  This is augmented even more with the 21 Limited.  I was about to try to rectify this problem myself with the above diagnostic, but got cold feet..

I'll wait to have Pentax do it.  Many of the tech guys at Pentax are still quite new to the K10D and I'm hoping that they know it well enough to solve this problem...I'd hate to have to use my Canon's for my next shoot.  I said that to Pentax and they freaked and said they would fix the problem on Monday...I guess considering my engagement with Pentax and the benefits, it is in their interest to solve this issue quickly.

The problem with this hack is that it fixes AF for the lens on the DSLR and apply these settings for every single lens mounted on the body. If the settings could be done separately for each lens, it would be much better.

That's far from everything. If you have serious FF, like many have in incandescent light, youre adjustments will lead to opposite effects in daylight conditions. I tried it myself, by adjusting my 17-70 with 120 um. Next day, the sun wa up, and all shots were out of focus until I aimed in front of the objects. Ergo, not only should it be lens specific, it should at least be WB specific.

It's a bit different if you need small adjustments only. Because with small adjustments, like when you have a little FF, only lead to small errors in focussing in normal light. But when you take picture in normal light, usually there is enough light to stop down the camera with one or two. DOF is big enough to get every sharp again. The problems start at dawn and at sunset.

Just like I wrote to you.

PS: Techs might not know much about this camera yet. If they figure out what the problem is for yours, that would be great. Others have reported bringing this issue up to Pentax, and have gotten no results with comments like, correct the focus manually after it stops, or one guy physically brought it to Pentax UK and they said it was "within parameters"! Showing him a few imperfectly focused snapshots of eachother's faces.

Ahhhh....Its who you know..

So, the solution should be to send the camera in with the lenses ? Hoping the techy guys know what they are doing ? What happens if I buy another lens and it FF as well ? Send it in again ? I really hope I do not get that famous disease..
