    Helical mount on my Focomat V35 is loose so when I change the aperture I bump the focus out. It is normally secured by a stop but for some reason is loose. How do I make it work?

    Regards,
    Dmitri

    Small knob #17 holds the focus helicoid in place. Unscrew to fine-focus, after focusing (if lens has rotated), loosen ring #18 in the manual. Rotate the lens to the correct position, then tighten ring #18.

    Which one does not hold #17 or #18?

    Locking knob doesn't lock it really.

    Thanks for your reply. It is helicoidal ring (15) that doesn't hold. It moves every time I change the aperture on the lens. There is no way I can lock the ring. And there is no click stop, it's smooth.
