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.

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...

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.

keep in mind though rota pola filter stages are for a circular filter... not 4x5.

Please forget that link. I meant to post another link: http://www.leefilter...p/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...)
