    Hi folks,



    Shrimpo here. I just fixed it. I used an engineers feeler gauge. The gap between the lens and the camera body would accept up to a ten thou feeler gauge. The one that fixed it was a three thou gauge. I needed to adapt it by cutting the end off square, tapping the end with a small ball pein hammer to make a slight ridge and then filing the gauge down to almost nothing at the tip. It worked a treat, slipped the spring loaded pin of the lens back into its seat and off came the lens.



    Anyone with a similar problem can leave a message and i'll come back with full details.

I fixed the problem. It was caused by an extra little pimple on the sirius lens slipping into the auto focus indent indent on the camera body.

It is possible to get up to a ten thou engineers feeler gauge into the gap between lens and camera body although the one that did it for me was a three thou gauge.

I needed to cut the feeler gauge square at the tip and then, even though it was only three thou, I hit the tip by resting on a vice and tapping with the ball end of a small ball pein hammer. This caused the tip to form with a small curve. I then used a tool makers file to smooth the end down to almost nothing.

Turn the camera AF MF switch to AF to raise the screw. Fiddle the feeler gauge into the slot between body and lens just near the AF MF button and very gently probe the gauge. You are trying to get the little curve you made on the feeler gauge to slip over the pimple on the lens.

Its a very nice feeling when the gauge slips right in and the lens comes free.

The next proceedure, if you want to use the lens, is to unscrew the aluminium mount at the end and remove the offending pimple on the lens.

You are probably right - it sounds like it is not connecting right - I would take it and the camera to the store and check out another lens!

I BOUGHT A PENTAX K10D THAT CAME WITH A VERY NICE AUTO ZOOM LENS. I OWN SEVERAL OLDER PENTAX LENSES THAT I USED ON MY K1000 CAMERA AND I WANT TO USE THEM ON THE K10D. I CANNOT FIGURE OUT THE SETTINGS THAT...


Hello,

I don't own a K10D, but I do own a K100D which I have successfully used both manual focus & auto-focus lenses from my old Pentax stash!

1) If it is a manual focus lens, you need to turn off Autofocus on the body of your K10D. On my K100D, there is a switch on the side of the lens mount that says [-MF or -AF]. "-MF" is manual focus mode & "-AF" is autofocus mode. Since your lens doesn't have autofocus capability, turn it to the "-MF" mode.

Also . . . When I press "Menu" and go to "Custom Setting", I change two settings . . .

1) I change "Using aperture ring" to "Permitted". This allows you to use manual lenses (M lenses) that do not have an auto(exposure) setting, and also lets you use Auto lenses (A, KA, KA2, FA, etc.) in either the Auto or manual aperture setting modes.

2) I change "Fl with S lens used" so that even with a manual focus lens, although I don't have autofocus capability, my K100D beeps and shows a little red square in the viewfinder when I have successfully focused manually!

The K10D should have the same options.

This should get you up and running!

I have had a load of fun with my old lens on my new digital Pentax!

Take care & Happy Imaging!

If this is a manual focus lens, you will need to do two things (and an optional third thing.)

1) On the side of the camera, you have to switch the focus mode switch from "AF" (Autofocus) to "MF" (Manual focus) . . . Yeah. I know, you probably already did that. <grin>

2) When you press Menu, go to the Custom Setting and change the Allow aperture setting to on, so that the Pentax K100D will then work with manual control of the aperture ring. You need to do this or the K100D will not work with manual exposure lenses (M lenses) or even autoexposure lenses (KA, KA2, FA, etc.) when you move the aperture ring from the "A" position to one of the manual aperture settings!

3) This is optional, but in the Custom Setting you can also turn on the Fl in manual focus mode, so that even though you don't have autofocus capability, you will get a beep indicator when you have successfully managed to manually focus your lens.

I have a few nice manual focus lenses that I have a lot of fun playing with on my K100D.

Take care & Happing Imaging!
