AM-M1 mount. What is that?

  1. Hello

    I was just browsing the certain well known bay, when I stumbled upon this strange 35 mm f/2.8 lens with "AM-M1 mount" attached to it. Mind you, that thing isn't removable, according to the seller. Here are the pictures:

    Here's the link to the whole thing:
    RARE Olympus Zuiko 35mm f/2.8 MF Lens with AM-M1 mount 50332503465 | eBay

    So let's forget the "very rare" part, I just want to know if anyone knows what that thing is. Or what it's used for. I'd think it's something related to medical equipment, since Olympus is well known for the knack of seeing what's inside a human body, but can anyone be moe specific? Why is the adapter non-removable, or why is it 35 mm lens and not something else?

    Thank you
     
  2. Nope, not a clue. But, I'm also not too inclined to take his word for it, regarding the fitting being permanent. And it's quite amusing that he's asking $899 for it, without even knowing what it's for or how it works, although he seems to think that it does work.The 0 feedback score doesn't surprise me, either.

    Having a quick google, I found this:
    LOG SUMMARY OF OBSOLESCENCE LETTER
    which is a list of equipment that company can no longer get parts for becuse their makers consider them obsolete, as of about 1999 (so maybe current equipment sometime in the 80s?) The AM-M1 is listed as a flexible gastroscope. Might this be a lens to record what you can see down your gastroscope?

    It also appears on UK ebay with a price of about 82 UK pounds.

    Nice job in finding the info! I looked a bit and didn't find a thing.
     
  5. Thank you for clarification. I suspected it had to do something with medical equipment, but was unable to search anything comprehensive on the net. As for the price, there was another sample for 120$ but the listing was endig in a few hours so I deliberately chose to post the link from the one that would stay a bit longer so people could actually look up what it was.

    I think the case is closed. Thanks again!
     
  6. Interesting. What exactly did you search on that retrieved that hit?

    Olympus are well-known for microscopes. The company history on their website talks a lot about endoscopes. So I tried 'Olympus microscope "AM-M1" ' and then 'Olympus endoscope "AM-M1" '.
    I don't know if AM-M1 is actually an endoscope, or that exact part; the lens with the mounting disc attached.
