Laowa Proteus Flex 2x Anamorphic 20mm T2 20mm
A fast T2 aperture and classic 2x anamorphic squeeze deliver pronounced elliptical bokeh and a wide cinematic field of view on S35 sensors. Its interchangeable PL/EF mount and user-swappable amber, blue, silver, or clear flare modules offer uncommon creative flexibility for a lens in this class. This lens is best for indie filmmakers and cinematographers seeking authentic anamorphic character without the rental cost of vintage glass.
