austinchimp Posted January 12, 2018 Share Posted January 12, 2018 I've managed to collect a few good c-mount lenses of different and unknown front filter sizes, and I was wondering if anyone knew of a good solution to mounting filters without a large matte box and without having to get unusual filter step up rings. Is there some way of attaching filters with a resizable or adjustable attachment on the front of the lens? Ideally I'd be able to use a 62mm filter for example, on multiple smaller c-mount lenses. Has anyone tried using anamorphic lens clamps for example? Quote Link to comment Share on other sites More sharing options...
Cinegain Posted January 12, 2018 Share Posted January 12, 2018 But... that's exactly why there are step up rings... You can get a set of them pretty cheaply. There must be one amongst those that will fit. Then place a sticker on the lens with the filter thread size for when you're using it next time. A clamp idea probably works too, you could even make one yourself, you just buy an attachment tube with filter ring for a compact camera and drill some holes in the base (or if there already are some, you might need bigger screws)... I 'm just not sure why you would though. Again, step up rings are there to negate said problem. Quote Link to comment Share on other sites More sharing options...
