Singh Ray Thin LB Warming Circular Polarizer (77mm) brand_Rollei this will not interfere withThe Singh Ray Thin LB Warming Circular Polarizer is a circular polarizer with a bit of a warming effect which is nice! This is the Thin LB version of this filter, which is thinner to stay out of the way of wide angle lenses, and also lighter and brighter to pass 0. 6 stops more light than other polarizers. In excellent condition, with pouch.
