Good, high-quality grey filter
However, the product appears to be high-quality; the frame is made of high-quality metal, presumably magnesium, and otherwise meets my expectations. An ND filter is used to reduce the amount of light entering the camera, for example, for long-exposure shots or in very bright environments when you want to keep the aperture open. This filter has an adjustable darkening factor that can be adjusted by turning the front part of the filter.
The quality is good and comparable to other branded products, as well as products from the K&F Concept brand, that I've purchased before.
The product arrived safely packaged and included three microfiber cloths made of fine, soft jersey material, which I didn't necessarily need, but they look good.
The filter was easy to mount on my Nikon Z50, but the thick ring on the filter makes it difficult to retrofit the anti-glare filter.
The image quality is good, and there are no color distortions.
Since the variable filter (like all filters of this type) is based on two polarizing filters that are rotated against each other, a polarizing filter effect appears in the photo, especially with slight darkening.
This isn't a bad thing, though, and is also the case with other variable ND filters. Polarizing filters are often intentionally used to minimize reflections, but it's something to be aware of. Unlike with regular polarizing filters, the polarizing filter layer here isn't rotatable.
The effects are visible in the example photo of a hedge. The image without the filter (left) is almost identical to the image with the filter fully darkened (right), with otherwise identical camera settings, except that I increased the exposure time from 1/10th of a second to 30 seconds. This long exposure time allows for good blurred shots of moving objects (water, cars, etc.). With the ND filter at its lowest setting (center), the polarizing filter significantly reduces the reflections on the leaves, making them appear much greener. I didn't take any photos of the other intermediate settings of the filter, but there are no significant color deviations either.
