Dorr DHG 中性濃度 ND3.0 1000x フィルター 52mm

Took this to the beach for some daytime long exposures and the 10-stop density really delivered—those 30-second shots at noon came out perfectly dark. The thread was smooth to screw on without any binding. A solid buy for the price.

Finally got those silky smooth waterfall shots I've been chasing. The 10-stop reduction is no joke, and the image color stayed neutral even with a 30-second exposure.

The math checks out perfectly—my 1/1000s shutter became a full 1s exposure with zero fuss. It’s a solid, dense piece of glass that threads on smoothly, and for the price, it’s hard to argue with the results.
