No issues with using this on Sony FX3 & A7iv

Exactly what I needed

I bought this to use with my new NOKTON 60mm f/.95. Even when shooting with wide-open aperture in midday lighting, this filter provided me all the stops I needed to maintain proper exposure while preserving detail and sharpness. The rotation is silky smooth, and responsive to small adjustments. My only complaint is the filter makes it a little difficult to keep the lens cap on, but this could be a issue with the lens cap, not the filter.

Works as advertised

was It has more flaws than good things about it. The vignetting is pretty bad, it also has a pretty gnarly green tint to it BUT! Since I shoot on Panasonic which almost always has this purple tint to it, this thing actually helps me with white balance.
