Vivitar 3-Piece Multi-Coated HD Filter Set (40.5mm UV/CPL/ND8)

I am using these in the corrosive environment of sea air. I use them primarily for protection of my lenses when I do not want to take the chance of trashing expensive filters or lenses. There may be a little less light transmission with the UV, but in the (most often) very bright lighting of the seaside this is not an issue. The other two are for the purpose of modifying light hitting the lens anyway, required by the bright harsh light of the ocean. Image sharpness is not effected unless you are looking closely at magnified images. No, they are not the best, but the price for what you get is good. Ocean air can etch glass, a dry salt crystal can cause cleaning scratches. Let that happen to these and NOT your lens. With some precautions I still hope that these will survive for a reasonable length of time. No complaints with the quality of their construction. These have a place and a job in my camera bag. I am using them on an Olympus TG4 while on dry land. They do require the use of an adapter with this camera. Beaches are great places to take pictures, just take care of your glass.

Buen producto en relación calidad y precio

très bonne qualité optique malgré le prix

Simply the best one available

Aunque el ND es fijo junto al polarizable no esta tan mal como filtros básicos para el lente kit
