Irix Edge Mms Neutral Density SrWork of a cinematographer is simply impossible without a proper neutral density filter. As cinematographers, we always aim at achieving "cinematic look" so we need to adjust the exposure value to the lighting conditions without changing other exposure parameters like shutters speed. Irix Edge Mms Neutral Density Sr magnetic filters redefine the concept of fast workflow on the set. Thanks to the innovative magnetic mount you will be able to change filters quickly and safely, thus work faster and more efficiently.Super Resistant (SR) optical glassThis technology makes the filter extremely resistant to damage - toughened optical glass covered with special nano-coating makes the filter survive virtually anything.Magnetic mount-smooth, fast and secure workflowIrix Edge Magnetic Mount System (Mms) filters have a strong magnetic mount that is compatible with Irix Cine lenses.
