Hoya ProND 2 Blendenstufen ND4 Filter 72mm

The glass is noticeably clearer than my old filter, and it doesn't shift colors at all. I’ve been using it for outdoor portraits to keep my aperture wide open on sunny days, and the skin tones look perfectly natural. Makes shallow depth of field much easier to achieve in bright light.

I was skeptical about using a 2-stop ND for landscape work, but it’s just the right density for smoothing out water motion without needing a tripod. The glass is noticeably clear, with no color cast that I can see.

Bought this to shoot portraits at f/1.8 in full sun, and it cut the light just enough that my shutter speed became workable. The 2-stop reduction is exactly what I needed, and the glass doesn’t add any weird color cast.
