NiSi P1 Prosories ND8（3級）適用於手機及輕便相機系統

I was worried about glare with phone filters, but this one's glass is crystal clear and the threading fit my clip-on mount perfectly. The 3-stop reduction makes shooting long exposures on my compact camera during daytime really easy.

Finally got the shot I wanted — this 3-stop filter let me blur a waterfall perfectly with my phone. The glass is really clear, no weird color cast.

I was worried about getting vignetting on my phone, but this filter is slim enough to avoid that completely. The 3-stop reduction let me blur a waterfall perfectly on my first try.
