Thanks

The Elmar has the normal A36 filter fitted and the pin is the screw fitting on the filter mount which tightens the filter on the Elmar lens.Then on top of this a SOOGZ adapter ring for E39 filters on A36 lenses has been mounted and then an E39 filter has been screwed into the SOOGZ adapter.
