Hoya Moose Warm CPL Overview

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).

This unique filter is the result of a collaboration between Hoya and respected wildlife photographer, B. Moose Peterson. It combines the advantages of a polarizer with the warming effect of an 81A filter.

Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems).

Does this have front threads for filter stacking?

Does this have front threads for filter stacking?
Asked by: chris
Yes, the Hoya 82mm Moose Peterson warm circular polarizer has front filter threads for stacking additional filters. Please be aware that due to the thickness of this filter, stacking more filters could potentially lead to vignetting issues with certain lenses (usually wider-angle lenses).

In the digital age is there anything a warm polarizer can do compared to a regular polarizer and warming the image when editing?
Asked by: Ernest
No not really, you can achieve similar results in post, but it is almost always better to expose the image as intended in the camera compared to in post. It gives a more authentic/natural and cleaner look.

how do I remove it? I thought I screwed it on, but now I cant remove it by unscrewing!
Asked by: Anonymous
It sounds like you may have screwed it in too tightly and the outer ring is probably spinning when you try to unscrew it. Please remember that it will be righty tighty lefty loosey. Try using something like a rubber band to grip the inner ring on the lens side and gently but firmly twist it in a counter clockwise direction as you are facing the filter on the lens.

Is the filter front-threaded to allow lens cap to be placed on it?
Asked by: J. Nixon B.
Yes there are threads on the front. I use this filter on my native Sony E-mount lenses and the original Sony cap fits fine.
