For the Sigma 12-24 mm F4.0 we have designed a filter holder for our 170mm filter system that can accommodate a 150mm round polarizing filter. The filter holder can accommodate a 150mm round filter in the default configuration. It can also be used for 170x170mm or 170x190mm rectangular filters. As the material CNC machined 6063 aluminum is used, which suppresses by its matt-black finish light reflections within the filterhaters.
With appropriate adapter this Filter holder can also be used with a Filter thread of 82mm or adapt less easily.
