The ND8 to ND128 filter covers a very useful range. There is no visible banding and very little colour change. More test are required to determine the performance in greater detail and different conditions, but I am impressed with the initial results, which show good consistency and accuracy of markings on the filter ring.

The item appears to be very well made and is nicely packaged. Having only recently acquired the filter, I haven't yet fully put it through its paces in all conditions. However, so far so very good. I haven't noticed any detrimental effects on image quality - no colour cast or X marks that afflict some other similar filters. It's just what I wanted and at a good price.
