Produced Consistent Results
The filter is thick but it is also larger than 67mm so the effective area is less affected by the thickness. I used Fuji 18-135mm lens to test this filter. When I set the focal length to 18mm (27mm Full frame equivalent) , I did not notice any vignette caused by this filter. Another test I did was set fixed aperture and shutter speed. Only thing that would vary was ISO. I then turned the filter to each ND level on the mark. I could clearly see the ISO keep moving up as the ND index went higher. When I compared the JPG results, I notched not much difference among those shots in term of brightness, color, or sharpness. So I would say that the filter is consistent within its intended stops. With these results, I would give this filter a go. With such a small package for 10 stops of ND, I definitely will throw it into my bag in travel.
