See this thread (assuming you have the latest 1.3 firmware): https://www.pentaxforums.com/forums/pentax-dslr-discussion/44804-k10d-debug-m...us-issues.html

If you have firmware 1.1 or 1.0, here are the instructions you'll have to follow:

1. Your K10D' firmware version must be 1.10.

2. Test shot for focus trouble.

3. Turn the camera OFF.
While pressing [PLAY]+[OK], Turn the camera ON.
You can see firmware version on LCD screen.

4. Firmware version is appeared,
then press [Fn]->[Fn]->[INFO]->[MENU] within 5 seconds.
You get service menu!!!

5. by pressing [right key]
,Make DEBUG MODE to DEBUG MODE .
then press [OK].
(save and LCD will be black out)

6. Press [MENU] and go to SETUP tab.
then, Press [Up key], you can see TEST MODE.

7. Select AF TEST menu. now you have AF correction menu.
If you have Front-focusing, reduce the value.
If you have back-focusing, increase the value.
after adjust some value, press [OK] and quit out of setup menu.

8. TEST for focus, find out that focus is correct.
(repeat this from 6 for correct focus.)

9. Go to service menu(step 3,4).
Make DEBUG MODE to DEBUG MODE .
then press [OK].(save and LCD black out)

The attached Zip has instructions (readme.txt) and a test image that work with firmware v1.20 (probably others as well).

That has to be the simplest method to turn on the Debug menu in the K10. I've have firmware version 1.30 and when I followed the instructions above, it turned on the Debug mode in my camera. This means that the Debug function wasn't removed after firmware v1.0 in the K10, but the method to activate it was changed, since the text commands in the text file wouldn't be able to turn on a non-existent function.

What I understand all you're saying is;

1. I have to copy this txt command to all my sd cards
2. I have to check and adjust all my lenses for best AF calibration with my body and note down the calibration value.
3. if I change a lens during shooting session, each time I change the lens, I have to start camera in debug mode, adjust AF calibration value according to the relevant lens in use.

Do I get it right?

No, not unless you really want the hassle of doing it that way. I would suggest that:

• You copy the text file to one of your SD cards.
• You calibrate the camera to the lens you use most often. The calibration will likely apply to most of the lenses in your "quiver".
• You erase the text file after you are done

If you have a wide range of variance in the AF between lenses, you might be better off upgrading your camera body or migrating to manual focus.

Pentax k10d v.1.30: successfully fixed backfocus for my FA* 28-70 2.8 AL zoom lens and the FA 100 2.8 macro lens by activating +70 AF-correction in debug mode. BUT ended with my FA 70-200 having severe frontfocus. It is a shame that the k10d-body does not have the option of setting AF-corrections for each lens separately. Is frontfocus a big problem for a long-range zoom like 70-200? I mean that I usually use it for shooting targets at large distances when all objects are in focus from target to infinity. In this case front focussing should not be a problem, or do I see smth. wrong?

I had issues with my k10d as well (using the most recent firmware).

Wrote an article about it after learned how to use the debug mode.

Good article, thanks! Remarks:
1) To make sure you are always focussing at one and the same point it is adviseable to use a special target (focussing chart) instead of rulers. There are tons of such charts downloadable from the internet.
2) I left "AF Area Test" at "0" and everything worked just fine. So the exact meaning of this parameter is still not clear to me.

[sjwaldron]

No problem.

Steve - the attachment doesn't work anymore can you repost?

[smigol]

You can download PK Tether and turn the debug mode on and off with a menu command. Much easier if you have a windows machine.

Great thanks!
