Title: SIGMA 55 UV Filter
Review: Does exactly what it needs to - reduce the blue flaring resulting from Ultraviolet light (with a small loss in crispness on some circumstances). Edging has teeth along with a texture paint to guarantee a grip on it. I have bought a few of them for various lenses and slipped right in place smooth+tight (Minolta Maxxum 75-300 + 70-210 "Beercan" and Canon Manual 35-75 Macro + 80-200 "Beercan")
Is the review positive or negative?
