My experience with the Filter holder for the Zuiko super-wideangle lens led to the design of a filter holder for the Panasonic lens. I took measurements of the lens and designed a holder for Cokin Z series or Lee 100 mm filters. The holder is designed to hold one filter only. I tried to design a mount for two filters, but the filters would have to be much wider. That is too expensive and the whole rig would be quite bulky. For a couple of years, I manufactured the filter holder in small batches.
Now, the mould doesn’t allow further casting. I therefore uploaded the filter holder to my Shapeways Shop. The new version isn’t that sturdy and that smug, but it is much cheaper and it’s still available!
The video shows the usage of the filter holder. Reinhard Wagner took it during a Olympus forum user meeting.
