ND filters are essential for some types of photography, such as moving water effects - and which I suspect I exaggerate a bit .... And of course there are millions to buy and a wide range of costs. I have tried lots from super cheap kinesium resin to some decent quality and now this. First and foremost, it's optical glass. And it makes a difference because the type of resin, although not bad if you treat it with the utmost care, tends to scratch easily, and of course the optical quality no matter what the text says is nowhere near as good as decent glass. Secondly, it is very well made. I mean up there with the stupid prices well made that I have tried and used in a well known camera store. This is a real 100% first class set considering the production standard and the general feel of it. Smooth in action with perfect optical clarity across the density range. In use it is super easy. Fit - which is smooth given the well-made thread and then rotates the outer ring to the desired level of darkness. It saves a lot of nonsense with different filters or stacking them. Honestly, if you want a good selection of ND filters (not graduated of course), then this is a good choice. I used it on my Zeis Batis lens and it worked a treat.

Bought this for a recent trip to Rome. Never got off the lens. good build quality and performance. worked silky soft, love it!

This is a well made filter that fits and works very well, excellent value for money as well.

A variable ND filter with the best value for money yet. Darker a high aperture compared to very expensive manufacturers. There are stops at the minimum and maximum, which I think is very good. Adjustment of the filter is done with a small resistance, which I also find advantageous, because unintentional adjustment does not happen so quickly with light touch. I have not been able to detect color fakes so far. Packaging very good and stylish. Everything perfect!

The filter looks valuable and the packaging is good.

I've had variable filters before, but I've never been happy with the dreaded Xs on the screen when spinning or the uneven color cast across the screen, and they's great, very even light reduction across the frame and no Xs. I have the 77mm filter, it is very well made, 77mm so no vignetting in the corners, the small disadvantage with it is that I can not fit the filter with my hood, but no big deal. We recommend.
