Summary:

The filter’s score was 12/45 points (24.4%).
Taking into account the previous ranking and omitting the homogeneity score, which wasn’t tested before, King Digital Slim would be the last but one.

The ring is the same as in the Digital King MC model – very low. Apart from that it differs from its cousin because it doesn’t have any coatings, it loses 10% of light and it lets much more UV radiation to go through. Frankly I don’t know what is this filter for.

The filter was lent courtesy of the Foto-Tip company.
