    After reading the previous thread I dug through old camera stuff and found a Cambron zoom slide duplicator from the 1980's, It would take universal mount adapters and has a Pentax bayonet adapter on it now. Can anyone give me a source for m4/3 adapter that would fit my Oly EM-1?. I wonder if it is the old 42mm Pentax thread as it's base configuration. Thanks!

    If it was meant to be adapted to various mounts it's probably a T-mount. T-mount to m43 adapters are readily available.

    If I remember correctly, T-mount has the same 42mm diameter as M42, but a different thread.

    Remember, if you want to copy 35mm slides, you want only 1:2 magnification, not 1:1.

    Probably a T-mount. It's made for FF so it will be 2X on m4/3 - only half the slide will be visible (zoomed in). Personally I started shooting slides with my Sony A33 & slide duplicator for it, but it wasn't worth my time. It's free, but paying 45 cents a slide/per 100 slides was better use of my time. The process was more time consuming than I thought, two evenings and I only got 85 slides done, doing 2200 more wasn't worth it to me.

    Thanks for the replies. Yes, T mount is what I was trying to remember. This will zoom to 1:2.5 so I think it will work.

    A follow up on the Cambron Zoom Slide Duplicator. I got a m4/3 T mount adapter and installed it. Well it works, sort of! It is out of focus unless I zoom out to 2.5 and that only covers a very small portion of the slide. I occurs to me that this was designed for full frame size cameras and the m4/3 sensor is just too small. At any rate, it only cost $18 US to find out:rolleyes:
