I use the UV filter as lens protection for my "Fuji FinePix S100FS" and has been able to find any negative qualities. More specifically: "No vignetting and no mirroring or ghosting". Actually, I wonder why a UV filter of other renowned manufacturers are more expensive by far and whether the quality is also many times is better? The workmanship is good, the up and down screw works fine. A second thread permits the use of additional filters.
For me there is a strong buy recommendation!
Addendum: I now also other favorable UV filter (HOYA) buy and was disappointed. Reinforced "Lens Flares" and "inclusions or impurities" in the glass so I again I ended UV filter at Tamron.
