Matt,

Try it in both landscape and portrait and let me know your thoughts.

What I don't realy understand is why there is a need to test, and potentially adjust, each and every lens. Surely the camera body needs adjustment, not the lenses.

Also, rather than focus on the thick black centre line of the focus chart, I lined the camera up on the left text column and focussed on the middle text string.

I've used my FA 100mm Macro lens at f2.8 for this so far. I'll try again later with a FA 50mm at f1.4, but the images from the DA* 16-50mm are very much sharper.

Damn, I should have done this ages ago.

I have to go out for the morning, back later with more info, hopefully.

A point just above the lower 10mm marker was sharply in focus. -40Um adjustment corrected it in landscape. In portrait, after the adjustment, the upper 2mm is more sharply in focus than the centre line is.

If I can correct that, I'll be a happy bunny.

Well I got brave and made the test and needed -40Um of adjustment to correct the focus in landscape mode. In portrait, it's still BF very slightly.

I'm using centre focus spot only for this test.

Q: Does anybody know if the vertical and horizontal can be adjusted separately. When tweaking the K10D, there are 4 AF test areas, are they individually adjusted?

Q: Does the K20D have these same 4 AF test areas?

What I've also noticed, since making the lanscape correction, just before I get focus confirmation, I get the centre red focus box lit, but also the top and bottom focus points flash for a moment. I'm guessing that that's because the focussing system sees all three points as being in focus. I don't get the same indication when the camera is in portrait orientation.

Any clues?

Edit: Having turned off debug mode, I no longer get all three focus boxes lighting up.

Selling, or just bought?

Both the Russian and English versions crash my (recently reloaded) WinXPSP3 PC. Both run OK on my USB1.1 only HP Pavilion 742 PC.

I've only used it so far to turn on and off debug mode. I'm not brave enough to do any more just yet.

I too have not been 100% happy with the focussing of my K10D, particularly when the DA*16-50mm is in use, which is most of the time.

I can't see any noise either. What I can see, occasionally, is some (moving) Moray fringing. But that's down to my monitor, not these images.

You can't. The web designers have decreed, despite our many protestations, that thou shalt not edit posts after 20 mins.

. . . and why haven't Pentax issued a firmware update for the K10D to allow this adjustment more easily, as per the K20D ?

It would probably take them less than 1 hour to make the change, and post it on the web. Result; Happier Pentax users.

Or are they hoping that every K10D owner will upgrade to 'fix' the problem?
