Re: Using the M42 Adapter?
First I want to thank all the members for their very helpful discussion and advice. What a great group. Well today I managed to get the Non-Pentax adapter out of the sacrificial PZ-70 without damaging the camera, especially to Derby Chang who provided the following link. http://www.funadium.com/m42tok.php#umount I now have two adapters, including a Pentax brand adapter. Cuz I am basically a coward I decided to remove the spring lock on both adapters. Tried them both on the PZ-70 and they went on and came off with no problems. I have an M42 Super Takumar 135mm f3.5 lens that I was eager to try out on my K20D. First I tried to install the off brand adapter directly to the lens but then it would not attach to the PZ-70 mount. Need to put the adapter in the camera first. Then used the pentax adapter and the lens attached as it should. Went out on the patio and did some test shots of sets of five (+/- .5) dial set to Av, f8. Downloaded shots to the puter and found that I needed a -.5 correction but I was truly amazed at the quality of the image. I am now convinced I am on the right track. Given that the adapters are relatively cheap I will get i per lens, remove the spring and using a automotive thread locker kinda permanantly attach the adapter to the lens. Will be looking for a 300-400mm lens to go after those migratory birds we will be expecting here in a couple of months.

Re: Using the M42 Adapter?
Be very careful using an adapter without a spring. Focusing a bit to energetically may cause the lens to dismount from the camera at an inappropriate time. I had that happen to me with an actual K mount lens I thought was securely locked in place...

RE: Using the M42 Adapter?
Ive used the pentax adapter for years with no problem. no tool is necessary to remove them from the k body, I just squeeze the spring to remove from body. just squeeze and turn, its not that difficult. p.s. the pentax adapter makes the k body into m42 body, it doesn't make the screw lenses into k lenses. -- J.C.

your plan wont work because if you remove the spring, there is no way for the lens to remain locked as you focus -- J.C.

Re: Using the M42 Adapter?
This happened on my MX and I had to undo the screws that held the K-mount to the body and remove the entire mount. At that point I was able to disengage the flat spring that locks the M42 adapter into the K-mount. After that I got a genuine Pentax adapter and discarded the third party one that had caused the trouble. That procedure was relatively safe on the MX which doesn't have any electrical contacts in the mount. With the PZ70 you have the complication of all of the AE contacts. I'm not sure how the contacts are held in place and removing the mount may result in a lot of very small and fiddly parts falling into your lap Paul.

Re: Using the M42 Adapter?
The contacts are probably held in place with very energetic springs, if it's like the MZ/ZX series cameras.

Re: Using the M42 Adapter?
It probably isn't stuck. You don't remove the adapter using the camera body release. Looking at the camera from the front there are two cutouts in the adapter. Inside one of them, I don't remember which you should see a black spring clip. You should be able to do this with your fingernail but a small screwdriver or pen knive blade works as well. Press the spring clip away from the camera body towards the adapter. while turning the adapter to the left as if removing a lens. It should release and pop right out.
