Originally posted by jacamar While the DA*300mm is a great lens, I feel this is a weak point in the design. You would think that the contacts would at least be bonded into place, but that doesn't seem to be the case.
Since it is a prime lens you will likely be attaching it or removing it relatively frequently, and on occasion the contacts can get bent. In the past I have had a broken contact and had to have it repaired. I understand that you can get the required parts and do it yourself if you feel confident in doing that.
A few weeks ago I bent one of my contacts in the same way as yours and I gently eased it back into place with a pair of tweezers. So far it's OK but I'm concerned that it will have been weakened. I suggest that you try easing it back, but it could well break, necessitating a repair.
Well, that's exactly what I did. My Son, who has steady hands and better eyesight, did it for me.

Originally posted by Basie I agree. I had the same problem as OP and managed to bend it back, but it was a little bit proud ( not bonded ) and promptly broke off. I tried to replace the copper strip, but it was integrated with the module. Since sending and receiving stuff cross border here is a financial nightmare ( you have to export, import pay export/import taxes etc) I contacted the camera repair shop in Cape Town that have the Pentax agency for repairs and they sent me the module for something like 20 USD after two weeks.It was actually quite easy to replace by removing the two philips screws and the lens is perfect again. The other Pentax lens ( 18-135 ) has the same contacts and I wonder whether was an over enthusiastic lens change or the longish lever from the 300mm that made it easier to damage
How does that happen, in the first place, so I will know what to avoid?
