The UV and CPL Magnetic Base Filter Kit Pro from Urth combines the UV Filter Pro and CPL Filter Pro in a convenient magnetic filter system designed for fast, seamless changes in the field. Both filters feature ultra-slim profiles to help prevent vignetting and 34-layer dual-sided nano coatings that repel water and oil while resisting fingerprints. The magnetic locking system uses the included adapter ring for secure attachment and quick filter swapping. Metal storage caps are also included for protecting the filters when not in use.
