Hoya Circular Polarizing Super HMC Filter

Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. PL (Linear Polarising) and PL-CIR (Circular Polarising) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarising filters do not affect the overall color balance of a shot.


How to select the correct Polarising filter:
Many of today's cameras use semi-silvered mirrors or prisms to split the light entering the viewfinder in order to calculate exposure and focusing distance. PL (Linear Polarising) filters can sometimes interact with these items to give unpredictable exposure or focusing. So we recommend that you choose a PL-CIR filter unless you have a manual focus camera which has no beam splitter.


Super HMC

These outstanding filters offer revolutionary performance in light transmission and color balance. 12 layers of Super Multicoating are applied to the surfaces of the Skylight 1B and UV(0) models, which produces an average transmission of 99.7%! Coupled with maximum surface precision, this allows increased resistance to flare and stunning images can be recorded at wide apertures without compromising the performance of your lenses. Our ultra thin Circular Polarising filters have seven layers of Multicoating applied to their rear surface to eliminate internal reflections and ghosting. Advanced thin selective film is used to guarantee perfectly polarised light with neutral color balance. Their slim profile of just 5mm avoids any vignetting problems and makes them ideal for use with wide angle lenses. There is no front female thread, but they do accept our push-on lens caps. HOYA Super HMC filters will appeal to the most demanding of photographers who require the ultimate in performance.

This group includes everyday filters which can be left on your lenses, such as Skylight 1B, UV and Polarising. These are the first filters that every photographer should ensure they own. Skylight and UV filters should be constantly fitted to a lens to give improved clarity and color balance as well as offering protection to your lens. Polarising filters have several uses such as ellminating unwanted reflections, increasing color saturation and enhancing contrast. As to whether you should use Circular Polarising or Linear Polarising filters with your camera.
