Carl Zeiss Zebra Pancolar Repair : glass clean & aperture blade clean / pixel valve /

I bought a broken Pancolar off eBay, It wasn't cheap, but It wasn't expensive either. It's an easy fix, but unexpectedly the item was not quite as described, the glass was scratched, so I replace the glass element with a better one and clean the rest. 00:00 Repair 12:40 Glass Elements
