NiSi PRO Protection Filter Overview

The NiSi 77mm PRO Protection Filter is a simple, clear filter with a 1x filter factor and is designed to provide general protection for your lens. This optically clear filter does not affect overall image quality while helping to prevent dust, scratches, moisture, and other substances from reaching or damaging your lens's front element. Additionally, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces to create an improved beading effect when in contact with water for greater cleaning efficiency.

NiSi PRO Protection filters are constructed from optical glass for clarity as well as color fidelity. This filter features a brass filter ring to enhance durability and jamming prevention.
