Is just Hoya

The above-mentioned filter is used by me on two objectives, firstly to a Tamron 70-200 and 2.8 on a Sigma EX AF-D 28-75 2.8. The quality is convincing. I have tested several filters at the beginning, Hama, Kenko, Fujiama but who wants quality gets stuck at Hoya at the end. HMC remuneration, reduced reflections, are the colors so again as they are (with no blue or green tint). From the construction of the Super HMC is beaten only internally by Digital Pro 1. Although it is slightly more expensive and is used by many only as a lens protector so you can tell the difference anyway. Top marks for the winner.
