فلتر Dorr 37mm Neutral Density 8 DHG

Used this for some long exposure seascapes and was surprised how little color cast it introduced; the ultra slim thread made stacking with a polarizer easy. Shots came out with nice, smooth water movement even in bright noon light.

Finally got around to stacking this on my 50mm and the ultra-slim ring sits flush, no vignetting at all even wide open. The 3 stops are just right for smoothing out a waterfall on a bright afternoon.

The ultra-slim thread makes a real difference — mounted it on my wide-angle without any vignetting at the corners. The anti-reflective coating is solid, cutting glare in bright sun and giving me that smooth, long-exposure look for water. Exactly what I needed for daylight shooting.
