Pentax MX Prism Cracked

Discussion in 'Pentax' started by bruce_varner|3, Sep 23, 2017.

  1. I own a Pentax MX that I am cleaning up. I saw what looked like spider web around the prism. Removed the top cover, and upon removing the prism, discovered that the inside of the prism itself is cracked in a spider web manner.

    Question is, can I use the prism from an old Pentax MX that I have sitting around to replace the existing prism in the MX?

    Thought I would not bother to try if I am told it is not the same size & shape…….. Thanks in advance.
     
  2. Ok, I screwed up. Should read:
    can I use the prism from an old Pentax :"ME" that I have sitting around to replace the existing prism in the MX?
     
  3. Someone suggested comparing the parts numbers between the two camera models. It appears they are the same. Now to see if the switch actually works........
     
  4. Good luck with it. Hard to see how this could happen though.
