On the Polish market, the King company’s offer is limited to caps, UV filters and polarized filters. Although the products are cheap, the “Made in Japan” inscription makes people trust their quality more. The King Digital Slim MC model differs from the King Digital Slim filter because it has multi-layered anti-reflexive coatings. Did it help to improve the weak result, reached by the filter without any coatings?

32/45 pts (71.1 %)

Summary:

The filter’s score is 32/45 points (71.1%).
Taking into account the previous ranking and omitting the homogeneity score, which wasn’t tested before, King Digital Slim MC would be 9th in the overall ranking, among much more expensive filters.

The filter ring is really low. Thin layers are not of the highest quality so their work is weaker at wider angles. It was also difficult to clean them. A significantly high UV transmission enables us to state that we deal here with just another lens protector with the “UV filter” caption. Its result is decent, though, and together with a low price it might suit some people fine.
