This UV filter is multipurpose and it is suitable for a colorful as well as for a black and white photograph. The filter also protects the lens constantly against water, grease and scratching.
UV VFFOTO filters marked like as PREMIUM SERIES are devoloped, designed and completed in the Czech Republic. The components are being produced in China.
Not only that they are equipped with 12 antireflective layers (6 on each side) but also they contain new 3+3 nanolayers with the most developed functions: improved resistance to scratching, water-resistance, improved resistance to grease, easier cleaning.
All of the filters in this series are produced using the first-class optical glass Schott B270 (more information about this glass can be found here).

Why you should decide for the VFFOTO PS UV filter:
1. 12 (6+6) antireflective layers of high quality = the minimization of objectionable reflections,
2. closing external treatment of the filter using nanolayers = resistance against water, scratching and impurities, these layers improve the mechanical as well as the physical qualities of the glass Schott B270,
3. original optical glass of high quality = it preserves even the finest details of the contours without having an impact on sharpness,
4. high transparency of the glass up to 99.8% = minimization of the loss of the light,
5. low design frame = it provides no vignetting, it can be used with the ordinary lens cap, it is suitable for wide angel lenses as well as for telephoto lenses,
6. a special hydrofobic treatment causes that the water drops are not spilling over but they are forming balls = the drop slips from surface by itself or it can be blowed out using the blowing balloon,
7. excellent price-quality ratio = a satisfied customer who will turn back,
8. precisely manufactured = reliability,
