VFFOTO NANO polarizing filter - in exterior:
Why choose the VFFOTO NANO magnetic polarizing filter:
1. very simple and fast change of filter without screwing,
2. 14 (7+7) high quality anti-reflective layers = minimizing of unwanted reflections,
3. final surface treatment of the filter with nanolayers = resistance to water, scratches and dirt, easy cleaning,
4. original, quality optical glass Schott B270 = not affecting sharpness, preserves finest details,
5. surface and side sealing of the polarizing film Nitto = protection of the polarizing film against moisture and adverse effects, its perfect tension between the glasses allows excellent image quality,
6. slim magnetic frame,
7. for a wide focal range of 24-800mm (converted to full frame) = versatile use, suitable for use on all lenses from wide-angle (24mm on full frame and above) to telephoto (800mm),
8. special hydrophobic treatment means that the water droplets do not spill but form balls instead = the droplet slides on its own or it is possible to remove it with an air blower,
9. glass filter does not generate static electricity = does not attract dust,
10. excellent value for money = satisfied and returning customers,
11. processed with precision = reliability,
12. slight color shift to "warm" = better psychological effect of the resulting images,
13. 2 years warranty - output control of every filter is performed in the Czech Republic.
