The thing I love about these ND filters is the quality of the glass and the housing. I have noticed very little if any color shift and zero vignetting. The latter has more to do with the design of the GoPro lens, than it does with the design of the ND filter. The filters came quickly and were packed well with no damage.I use the ND32 filter the most on very sunny days in Southern California and utilizing the 180 degree shutter rule, I am able to achieve an acceptable exposure.
