    Need Help - 105-210 Af problem with DF

    Hi everyone,

    I recently bought an used but Exc+ Mamiya 105-210 AF for my Aptus II 10/DF (could not afford 75-150 D unfortunately).
    But the Af didn't work and the lens isn't recognized from the DF for a (long) moment and after a while said i could open it at f/2,8... hey nice then f/1...YAHOO my new jewel and finally f/4,5 but the AF wasn't working anyway.

    The DF firmware is 1,21 so correct.

    I tried with my dealer another DF... same thing. I put it an Mamiya AFD, miracle, everything worked fine.
    I think there is an upgrade to do with the lens but don't know how to???

    Sure you could help me.

    Thanks

    Sounds like your dealer missed the memo :-P.

    Most 105-210 lenses just need a firmware update which will be free or a nominal fee by your local Mamiya distributor/repair-center.

    Some early 105-210 lenses had a different AF motor system than the rest of the AF lenses and will require a hardware upgrade which, off the top of my head, is something like $400. This is the only AF lens with this issue because of a unique focus motor they used early on in the 105-210 production which is not supported by the DF.
