Haida Circular Polarizing (C-POL) Filters use an excellent quality neutral polarization material, without any color cast.
Using special techniques, the filter material is bonded together with optical glass, and fused with special crack resistance treatment.
When using a polarizing filter, a smooth rotation is needed optimally set the filter to take brilliant pictures. Ordinary CPL filters could easily get frozen when in low temperature, or lose the comfortable damping feel in high temperature. Haida's special processing techniques guarantee each CPL filter has the steady rotating function between -40° and 80°.
In addition, an excellent quality CPL filter must be able to withstand extreme temperature differences, for instance, deep inside a rain forest where it's hot and wet, or out in the mountains where it's freezing in the winter.
Under these circumstances, an ordinary Polarizing Filter may cause problems of forming air bubbles or show signs of adhesive failure. Haida's special strict processing techniques ensure that all these will ever occur.
Available sizes: 52mm, 58mm
