Premium Member Phil Rhodes Posted August 13, 2014 Premium Member Share Posted August 13, 2014 Title says it all, really - does anyone make a device that allows a 4x4 filter to be continuously rotated in front of the lens? It'd need to be silent. P Link to comment Share on other sites More sharing options...
Premium Member Gregory Irwin Posted August 13, 2014 Premium Member Share Posted August 13, 2014 Have you considered the below example of a 4x4 tray that internally rotates a pola filter? I would imagine you could mount whatever you want in this tray... http://www.abelcine.com/store/RotaPola-4x5.65-Kit/ Link to comment Share on other sites More sharing options...
Premium Member Dom Jaeger Posted August 14, 2014 Premium Member Share Posted August 14, 2014 There are plenty of matte boxes with 360 degree rotating 4x4 stages, but they tend to be noisy and not designed to be smoothly or continuously rotated. The RotaPola filter holders Greg linked to seem more like what you're after in that you can hook a follow focus or motor up to the turn wheel and they rotate pretty quietly, you'd just need to source circular filters to fit in them.

Albion Hockney Posted August 14, 2014 Share Posted August 14, 2014 keep in mind though rota pola filter stages are for a circular filter... not 4x5. Link to comment Share on other sites More sharing options...

Joerg Polzfusz Posted August 14, 2014 Share Posted August 14, 2014 (edited) What about this one? http://www.owis.eu/en/products/motorized-positioning-systems/produktgruppe/filterraeder/produkt/8/productview/Main/ Please forget that link. I meant to post another link: http://www.leefilters.com/index.php/camera/system Unfortunately I can't edit my post any more. :-( (There are more rotatable filter-holders from Lee and other companies. So there must be one that's suited for your filter. But I haven't found any motorised versions...)
