Help needed on m42 genuine pentax adapter

netuser · 11-19-2008, 10:39 AM

Today I got a problem with the original pentax adapter.

Was using on a lunch time with a paragon 500mm f8 on k200d, and when tried to unscrew not only the lens (lens got stuck with adapter as it seems) but also the adapter got out from camera.

Now when I tried to use the adapter it just doesn't lock on the camera. Seems it work like I add removed the lock pin / spring clip from the adapter.

Any ideas ?

(Have to see how I will unscrew the adapter from the lens...)

Do you have any pics of the backside of the adapter? (the part that seats in teh camera body)

The only thing I can think of is maybe the spring got snapped off (or fell off) since there's just a very small screw holding it in place

Weird stuff happens

I expect that the 500mm lens is rather heavy, and maybe the weight of the lens caused some sort of problem with adapter. Largest (heaviest) lens I have is a Super Tak 200mm and it has caused no problems.

Pardon if it's a silly question, but is that a T-mount rather than an m42 lens? The threads are pitched differently.

If it is, you can just get a K-mount T-mount adapter.

I find it better to put the ring in the camera, then screw the lens in.

Some would disagree, but this way, the ring doesn't come off with the lens.
