My Pentax M42-K adapter got stuck on my Takumar 200mm F 3.5 lens, so I figured that I might as well leave it there and purchase another one. So as I searched the web , I noticed that the price for the M42 adapters had shot up by $25 - $30 on B&H and Amazon. I tried Adorama, but could not find the Pentax original M42 adapter so I opted for a third-party brand, a Kipon (made in China) for $17.79. Knowing fully well of the horror stories people had with these third-party adapters, I ordered one anyway based on the excellent reviews for this adapter listed on the Adorama website.
When it the Kipon adapter came in the mail, I decided to try it with all my Takumar lenses. Everything seemed OK until I tried to take the adapter off the camera, but could not. I tried everything, but the adapter would not come off no matter what I did. I searched the fancy box the adapter came in for instructions, but there weren't any ! By then I was in panic mode !! I was seriously thinking about calling Adorama and give them a piece of my mind, but it was too late, the store was closed.
My only hope was to remove the front metal lens mount on my K-5IIs to see if I could remove the adapter this way ? The front metal mount on the K-5 IIs is held by 4 screws that are pretty easy to take off, but you have to be really careful that you don't scratch or drop anything into the camera while doing this. Behind the metal mount is a flexible thin copper plate that is attached by a really thin wire to the camera with solder, not sure what purpose it serves ? Unfortunately, while I was trying to remove the adapter I separated the thin wire from the flexible thin copper plate ! I did mange to remove the adapter from the metal mount though...
I figured
oh no ! I ruined my beloved K-5 IIs and after the holiday season did not really have the funds to get it fixed. While I was seething in anger and despair, I decided to re-install the flexible copper plate and the metal mount back on the camera after some trial and error. To my surprise the camera still worked ! I tried all my DA/FA lenses and everything seemed to be working fine. Also all the functions seemed to be working as far as I knew. So then what is the purpose of the thin wire attached to the flexible copper plate ? If it is an important function maybe I can try to solder it back, or have it repaired sometime in the near future since the camera works and there is no rush.
To make matters worse after reinstalling the front Metal Mount and flexible copper plate the best I could, I found the tool that is supposed to be used to remove the Kipon adapter from the camera ! It was sitting under a pillow on my living room couch. Since the adapter came with no instructions I didn't know it came with one... Regardless, I'm too afraid to ever put that adapter back on my camera. I immediately ordered the original Pentax M42 adapter that was listed on the Adorama website, but which I could not find the first time I searched for it ?
To make a long story short, now my only problem is the separated thin wire from the inner flexible copper plate that goes behind the Metal K-Mount. Maybe I can solder it back myself. Does anybody know why that wire is attached to this copper plate and what function does it perform ?
