At last I have found the right UV or protection filter for my digital SLR. The Hoya filter has previously slightest reflections, the glass is absolutely flawless, the remuneration excellent (no streaks, no Eischlüsse and to the brim). The Protect-coating can hardly cling dust and water runs cleanly. Falling directly into the front lens light, it is nevertheless advisable to refrain from these or other filter all, depending on whether you can live with light flares or not.
