Question about Cameras
I have a sirius 18 to 28 mm ka mount lens jammed on my pentax k100d super
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.
