Hi,

I have big news!

If your K10D have problem with focus, you can adjust it yourself.

Someone in Korea figured it out himself.

He is not a employee of Pentax or related company.

He just found out by trial-and-error with key-set.

Of course, You yourself is responsible for doing something scribed below.

Here's How-to-adjust-focus.

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)

10. Go out and enjoy nice photos!!!

AGAIN, You yourself is responsible for any damage or trouble by doing this process!!!!!!!!!!!!!
