Hey guys, I think I have a s16 zeiss 12-120 zoom on the way soon. I mainly work super run and gun and will do pretty much anything to avoid using a matte box. I believe the outer diameter of the lens is a standard 80mm so I'm sure I could use a snap on shade with round filters. Ideally though, I'd love to use normal screw on filters. I've been having a hard time finding out if these lenses have threads. Does anyone know if they do and what size they are?
