Skyler Carrico Posted January 23 Share Posted January 23 I'm trying to get some ND filters for a 12.5mm and a 17.5mm Cooke Kinetals I just purchased prior to receiving them. I can't find any information online on what the front thread size is. Anyone have these lenses who can tell me? Mine will be Arri-Standard mount, in case that matters.

Eric Eader Posted January 25 Share Posted January 25 Skyler, KEH shows a 17.5mm Cooke for sale and indicates the filter size is 48mm. That means you will need a 48mm step-up to Series 7 adapter at a minimum. (Or 48 to 52mm for Nikon screw-in ND & B&W filters). Look first for Tiffen adapters then Harrison but look for Tiffen retaining rings as Harrison did not usually thread the retainer for a lens hood or extra filter add-ons. (eBay shows Tiffen rings for sale). Kodak made excellent filter holders but being steel are quite heavy... and durable!! Of course if you have or find other brands that work go for it. (I don't know if both lenses have the same thread size like more modern standardized lens fronts). Hope this helps. Link to comment Share on other sites More sharing options...
