Used: 30mm PQ fisheye lens for Rolleiflex 6000 and Hy6 cameras
The 30mm PQ lens is pretty rare, and it's even rarer to find one in this clean a condition. I had two at the same time and they performed very close optically, but this was the nicest so I kept it. It comes with both caps, original box and the filter set. The lens actually splits apart into two halves such that a filter can be fitted. There is a release button and a collar ring. You push the release button and twist the collar to unlock the lenses halves to open the lens. Then when you refit, you match the red dots to align the parts then carefully set the top part into the base making sure the little pin fits into the slot. Slowly tighten the collar and it will pull the two halves together. Note that there are actually 4 filters as the UV filter is already fitted.
