Breakthrough Photography 49mm 6-Stop Dark Circular Polarizer Filter

Breakthrough Photography is introducing a ND and CPL combination filter which they call a ‘Dark CPL’. “Stacking ND and CPL filters is a common scenario for outdoor photographers. But the primary drawback of doing this is vignetting at 16mm on a full-frame setup. The Dark CPL is compatible with the following camera and lens systems: Leica Carl Zeiss lenses Schneider Xenon Canon Cinema and L lenses Nikon Sony Fuji and others.SCHOTT B270 Optical Glass Filter Type
