Slip-over lens cap for most 55 mm filters sold by SRP except for the 55 mm SRP CP-MC, 55 mm SRP CP-WR, 55 mm SRP ND8/CP, and the 55 mm URPRO CYD filter.
SRP only sells ultra-low profile filters to minimize or eliminate mechanical vignetting in all GoPro modes. This means a standard clip-on lens cap will not work with our filters. This lens slips over the filter. Protect your filter investment and make sure your filter is clean when its time to record by using a lens cap.
