stucked PL mount!

[Karim Iglesias]

hello, last friday I mounted a super 16mm zoom lens its was very cold about
-6ºC, later the temperature went up at about 12ºC when we tried to change lens we weren't able to open the mount, Its was stucked

I think because the cold the metal was contracted and the mount was overtightened and then when the temperature went up expanded

please if somebody had this problem before, tell me how to fix it

Thanks

Karim

put the camera in the freezer? Really, try carefully to bring it down to below zero.

Had this happen to me too

This happened to me as well. I gave it time over night and then carefully used a more force to turn the locking ring.

Try tapping (lightly and counter clockwise) the locking ear(s) on the mount with a plastic face hammer. Sometimes the light impact is better at getting the locking ring to release then strong arming it by hand.

Strap wrench.

Chuck, I read this post and that is exactly what I thought how to take care of this. We think alike and it also comes from experience from these exact situations. Just make sure you are using a plastic or hard rubber tip hammer and make sure you are hitting (hard tapping) in the proper direction. Works like a charm.

Yeah Steve it does come from experience. Use to have, oh mayby, eight or nine hammers in my tool boxes. I think the heaviest was an eight ounce ball peen for setting different retention pins.
Also nothing wrong with using a strap wrench either. I just never had one.
