had found a great deal for Sandmarc lenses online so I grabbed them. But for outside filming I need an ND filter due to the bright California sun. I got a lens adapter for Sandmarc but they use 40.6mm. Probably so you have to buy their expensive lenses and filters. I am not a professional to warrant an expensive filter so I tried these with 40.5. AND they fit. I cant judge the quality since I have not used them.

The filter is fine, it does what it promises and allows you to use the Sony ZV1 in manual mode, blurring the background. The truth is that it works well, but when you put the filter in the maximum darkness, approximately ND400, you can see the intersection of the filters, but there is nothing to worry about because in video, one reaches a maximum of ND 64.

Worked really well and was super impressed by how much it blocked out this light. Unfortunately, I purchased the incorrect size for my lens. Looking forward receiving the right one and putting it to use!

love this variable filter that I use on my Nikon D5600 DSLR. I’m an amateur photographer, kind a “B-minus” student on the technical side of things. But, I do enjoy, and am getting fairly good at, various long-exposure techniques including ICM, which can lead to blown-out/too brightly-exposed sunny outdoor shots. Learned about ND filters in my photography class. Apparently, you can take your shutter speed and aperture settings and pump them through an algorithm to determine where to set your ND filter, or which non-variable filter to use. Too complicated for me. When I set my exposure length and aperture settings with the ND filter at its “Min” setting, then point my camera at a sunlit subject, my camera will flash “Subject Too Bright”. I just start slowly rotating the variable ND filter’s ring toward “Max”. As soon as that “Subject Too Bright” message goes away, I know it’s OK to release the shutter. Perfectly exposed shot every time with this inexpensive variable ND filter.

Would recommend works just as advertised it’s lightweight , smooth transitions and it does not hurt image quality in my opinion and works great for long exposures in the daytime
