Focussing 50mm on K100D
Welcome to the forum Charlie. First, Is your lens manual or auto focus ? If it's manual focus, you'll need to turn the focus ring to focus on your subject. Also, the aperture ring will only have any effect when your camera is set to M (manual) exposure mode. In all other modes the image is ...

Focussing 50mm on K100D
It's manual, so i'm turning the manual focus ring! :) Things appear sharp in the viewfinder but they're quite soft when viewed in full. Does the camera control the aperture automatically, even if it's an old film lens?

I recently purchased a 70mm f2.4 ltd lens for my k10d and found the out of focus. I use centre point focus and wide open. The images were out of focus in the centre. I went back to the shop and he took a photo of text at an angle and it looked ok so he refused to change it. It wasn,t until I had...

Our resident genius Matt Mattic is probably the man to talk too. He fixed his K10 when it was back focusing. Something to do with a firmware hack if i am not mistaken. If its still under warranty i would ask for a replacement.

Thank you for your replies. I have looked at the hack info but the problem is that i have a mac and the software is for PC. I still have warranty but I am loath to let them touch it as they have tried twice already and it's still not focusing plus I thought to set the focus the camera should be se...

Do a forum search "back focus" and you will find all the relevant information. How did you do this, John? I searched on those keywords, and got many pages returned, and finding the relevant ones was exceedingly difficult (I gave up without success).

If I remember correctly there have been two "guerilla", non-official, methods for focus correction on the k10D and neither are for the faint hearted. The first one was that someone leaked the key sequence for debug mode but it only worked on firmware version 1.10. Normally you can't downgrade the...

I just tried the Russian programme, without camera attached. I pressed the top left button, and my PC (WinXP Pro SP3) crashed.

I just tried the Russian programme, without camera attached. I pressed the top left button, and my PC (WinXP Pro SP3) crashed. I tried it, with XP Pro SP2, with the camera attached. Seemed to work fine (got the debug mode message on the LCD), although I didn't have the bottle to change anything -...

I just tried the Russian programme, without camera attached. I pressed the top left button, and my PC (WinXP Pro SP3) crashed. I tried it again, same machine but with camera attached. Same result, PC crashed when top left button pressed. I guess I'll try it on a XPSP2 laptop then. I don't think a...

Hmm well I found this some time ago: 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, Y...

Thanks again for your suggestions. I decided as I still have a warranty that I should let them check it again. This they did and told me that the camera was slightly forward focusing and that testing the camera with the chart in a position where the camera is pointing down at a 45 degree angle wi...

That's all well and good. Now kindly explain how to install firmware version 1.10 onto a K10D which has current firmware. G It's been done, I believe it was hacking the hex file and changing the string that had the version identifier in it. Or summink like that, I'm sure someone has the fully ...

That's all well and good. Now kindly explain how to install firmware version 1.10 onto a K10D which has current firmware. Just out of interest, other than getting into Debug mode without using an undocumented Russian program where all the buttons are in Russian, why would you want to regress th...

why would you want to regress the firmware? Because you can't enable the debug mode in anything but 1.10. All versions above 1.10 require a USB connection to enable debug mode. v1.10 had the complicated-keypress-sequence to get there, so you could do it without a PC. TBH, it's not difficult eith...
