    It was dinged up, front element was scuffed to hell, don't have a M42 adapter, etc. I originally took it apart to get at the aperture assembly (had some ideas about piecing together something).

    Once I got it apart realized the aperture housing is one solid piece and I could screw the back element of the lens back onto that. So temporarily I taped it to the LTM adapter I have since it was roughly the same diameter to be able to just tape it on without it wiggling at all.

    working distance of about 6-7 inches, it's got quite a bit of threading on the rear element so in theory you could unscrew it slowly to get some fine focusing on a tripod.


    *Edit* as I was typing this the cat decided to be an ass and picked up, pushed and nocked it off the desk behind me thus cracking the edge of the rear element. *glares at cat, not the first time she did this...*

    Apparently if I flip around the rear element so that it's facing in the normal direction towards the lens, but much further out from the sensor I can get almost normal-ish focus range (like 6 to 12 ft from me). I'm experimenting with the possibility of rigging it up on something like a crush tube to make an extremely poor version of a tilting lens baby (so far it's worked a lil using stretchable electric tape.)

    That is pretty darn cool. I admire the ability to dismantle a lens and make something of it.

    Mount type

    I'm not sure, does the Mamiya 645 lens use and M42 mount? Do anyone know of an Adapter for these lens to MFTs? :rolleyes:

    You would just get a Mamiya 645 -> Canon adapter from fotodiox, then Canon to Micro-4/3 from fotodiox as well.

    Or can go with the M645 to Nikon one and then use the Nikon to M4/3. (except the EOS route you could get the one with it's own built in aperture).

    PS: the above sekor is not 6x4.5, it's an old 35mm. Sekor wasn't just used on one line of cameras/lens.
