The 77mm NanoPro Magnetic UV Protection Filter from Haida is a clear filter that provides general protection for a lens without altering the image quality. The filter features optical glass and is coated, making it resistant to water, oil, dust, fingerprints, and scratches, and it protects the lens from such elements and damage.

The filter magnetically attaches to the included magnetic adapter ring, allowing easy mounting and removal. First the adapter ring screws onto the front of lenses that have 77mm front filter threads, and the filter magnetically attaches to the adapter. The filter and adapter together weigh less than 1 oz.

The adapter can be left on the lens at all times, and it supports standard 77mm lens caps when the filter is removed.
