Wide angle mallincam new
      #3390876 - 10/15/09 10:09 AM

Has anyone got any experience with using the mallincam with a camera lens (I see Rock is about to sell such a lens). How well could the mallicam be used unguided for very short focal lengths?

Will check it out? What adapter are you using to connect the camera to the lenses or are they native for the Mallin (?Mallin has a C-mount thread on the front?)

Thanks
