Heliopan Circular Polarising filter is available in Standard and Slim versions. Not all filter sizes are available as Slim type.
Slim type has no front filter thread so a lens hood or lens cap cannot be used but is about 1.5mm to 2mm thinner.
Heliopan Circular Polarising Filter. The Circular Polariser is suitable for use with all Digital and AF cameras, as well as manual cameras too.
This filter is coated on both sides with a anti-reflective scratch proof metallic oxide coating. Even superior is the version with the special SH-PMC Multicoating.
Polarizing Filters reduce reflections and glare, they are a neutral color and can be used for color or black and white imaging. As the light coming from the sun is not polarized parts of the light become partially polarized due to the scattering of particles in the atmosphere.
This scattering reduces the transparency of the air and creates haze in the distance and the blue in the sky on a sunny day. Polarization also controls in the reflections of light on the original color of the surface.
The Heliopan Polarizer improves the color of the sky, (in distant pictures, mountain scenes, etc.) it reduces the bluish cast in landscapes and increases the blue color of the sky. The effect is strongest at a 90? angle to the sun. In addition polarizers enhance the color saturation of the scene by suppressing the reflections on the surface, undesired reflections are largely eliminated.
For brilliant color reproduction, highest contrast and sharpness Heliopan filters are THE choice for the professional photographer. When coupled with the fact that Heliopan filters are manufactured from SCHOTT glass (the same stuff used to make ZEISS optics), it is clear that the only thing that should stand between your lens and your subject is a Heliopan filter.
