William, I did not follow the whole thread but some at DpReview managed to hack the header of the firmware allowing one to downgrade from 1.11 to 1.10 (in fact 1.10 with hacked header) and then official 1.10 firmware.

I read the fellow's paper (for the life of me, I don't recall his name), and he took quite a bit of effort to debunk the naysayers. Pretty much, it came down to the camera not knowing or caring if the test chart is on an angle, since it is only being asked to focus on a discrete line on the page. I used diffuse daylight. If the light spectrum makes a difference, then one should run these sorts of tests in the light type used most often. My own thought on that is people who don't know how to run a test shouldn't be running tests.

Re: K10 Debug Mode
Ok, it's still light enough here that I was able to do some more testing. I put the 14/2.8 on the camera and did a focus test with it. Totally out of whack, though in the same direction as I was moving with the 31mm. So, I did another adjust until the 14 looked good, and tried again with the 31. The 31 looks perfect as well. I'll do some general photography tomorrow and see how things look in the real world, but I am confident I just raised the resolution of my camera significantly.

Just out of curiosity which way was it out + or -? Cheers, Dave On 3/17/07, William Robb [EMAIL PROTECTED] wrote: Ok, it's still light enough here that I was able to do some more testing.

I made a rather large + correction, 180 um to get it to where I was happy. It's funny, I've not thought this camera was doing as well as it should, based on the quality of lenses that I use. It would be interesting to know what Pentax feels is a permissable AF offset amount is before one starts doing mechanical adjustments to the AF sensor position.

You are correct. Rick Womer wrote: I appear to have missed something. Does the updated firmware lack the calibration mode? --- William Robb [EMAIL PROTECTED] wrote: - Original Message - From: Tom C Subject: RE: K10 Debug Mode Interesting. Nice that it's adjustable, sad that it comes that way... out of calibration so to speak. Is the focus adjusted at just one distance from the focal plane or is it done at varying distances? I downloaded a chart that some guy with a D70 made. It's printed off on an 8.5x11 sheet of paper. I used the 31mm, at about a 2 or so foot range. I haven't checked focus with any other lenses yet, that will be my project for tomorrow.
