Polarizing Filters give you the ability to control how much of the reflected light gets into your lens at an angle of shooting from 40 to 70 degrees from the reflecting surface to the polarizing filter. So you can reduce, eliminate glare completely, or vice versa enhance polarized light, rotating the polarization of the ring on the filter. This effect is particularly noticeable when shooting glasses, fish or bottom of a small layer of water in bright sunlight, texts or pictures under glass or protective glossy layer of lacquer. 

Every object outdoors reflects sunlight to a greater or lesser extent, scattering and polarizing it, similar to the 82mm. Some objects, such as green plants, bushes, grass, red tile roofs, metal (coated) covered with bluish-grey veil that can do look pale and dull. Polarizing filters like the 82mm circular polarizer, remove this veil and achieve saturation and natural colour, even in such difficult cases. The light coming from the blue sky, especially when the angle at which the sun's rays falling near or straight, is strongly polarized, while a polarizing filter can be used for transmission of the sky with a more intense blue, with white clouds remain white, which makes the image more attractive and dramatic.

The 82mm circular polarizer filter allows you to change the view of the usual things; to remove what can not "see" the usual matrix or film ... 

Circular Polarizing filters are made from special optical glass with unique bandwidth. They delay the reflected rays, which are reflected from certain surfaces polarizing, while saturating colours. Reflections from metallic surfaces polarizer do not delay. 

Conventional its scope - it is certainly shooting landscapes, when the polarizing filter saturates the colour of the sky, makes bright tiled roofs, the water becomes transparent ... see the bottom and floating fish. Also, shooting through the glass, shooting leaves and grass, which are also quite strongly subject to the influence effect of the reflected rays. 

Polarizing filters are divided into two subspecies: Linear - (linear) and circular (circular) - (Circular). 
The second type - circular - is designed for use with cameras and lenses with auto focus, E-TTL and i-TTL and so on. Variations electronic metering. 

This model has a diameter of 82mm. 
Implemented in a standard classical frame thickness 1, 10 cm (with an internal thread). 
In the manufacture of glass used an innovative solution - a system SH-PMC, including a 16-ply two-sided multi-coating (only 32!) To exclude the effect of glare and internal reflections on the final result with an external waterproof layer that prevents drops of water trapped on the glass. 
The scale divisions on the rim for ease of use. 
Suitable for all analog and digital cameras.

Heliopan - German manufacturer of optical filters using in their production Cylindrical billets of the highest quality of glass produced by Schott Group (Zeiss) - the world leader in its field. 

Heliopan 82mm circular polarizer filters are ground, polished and reflection coatings in full accordance with the highest standards in the optical industry in Germany. To prevent collapse thread and ensure optimal alignment, all Heliopan filters are installed in the exact production, anodized black with brass frame.
