The Hoya low profile circular polarizer takes advantage of Hoya's patented optical glass technology to create a hardened glass that is thinner than the normal optical glass. This allows the overall thickness of the filter to be reduced to avoid vignetting when used with ultra-wide angle lenses. The Hoya Super-HMC PRO 1 low-profile frame is a slim 5 mm, making it the same size as a regular Hoya filter frame. Standard Hoya circular polarizer frames are 7.5 mm thick where other manufacturers are as much as 10 mm thick.

Beskrivning
Another advantage to the Super-HMC PRO 1 Circular Polarizer is it has normal front filter threads meaning a normal clip-on style lens cap may be used. The Super-HMC PRO 1 Circular Polarizer has a 6 layer Hoya multi-coating, the most used in the industry, applied to the front surface of the filter to greatly reduce the chance of lens flare or ghosting caused by reflections.
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Filter factor is between 2.3 and 2.8 (approx. +1.3 stops).
Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems).
Filters in this series use our new ULTRA thin rings which, like the Super PL-CIR filter, are designed primarily to avoid vignetting problems which occur with wide angle lenses. The ULTRA series filters use rings just 3mm in thickness, except for the hybrid UV/Polariser which has a 5mm rotating ring. HMC Multicoating is applied to both sides of the filters and they are supplied with our push-on lens caps. The Ultra ND filters use new Multi-Layer Coating technology to produce a neutral transmission curve which gives perfect color balance. We have also introduced hybrid filters in the ULTRA series, these combine the effect of two filters in one (i.e.: PL-CIR and UV together). This means that HOYA ULTRA series filters are the ultimate choice for wide angle lenses - there is no other filter available to exceed the ULTRA
