The Hoya 58mm HRT Circular Polarizing Filter is unique in its design since it incorporates a High Rate Transmission film that permits more visible light to be passed through the filter while still producing the same degree of polarized light. This filter now permits the equivalent of 1/3 stop more light to be taken in yet it still filters the same amount of polarized light. This can be a huge benefit to users of both digital and HD technology cameras and lenses.
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.
This filter also contains UV properties which aid in eliminating the bluish cast on cloudy days or in open shade.
Polarizers should be a part of every photographer's gear. They are useful when you wish to increase the saturation of a blue sky or want to make the clouds stand out more. Moreover, they are handy when reflections are a problem - such as when shooting into glass or on the water.
All of this goes into increasing contrast for a more effective photo. The effect of the polarization 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.
Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems)

Simply a great polarizer
I use the polarizer primarily for landscape photos and was impressed by how much my photographs improved by simply adding a filter!

The idea of allowing more light through the filter made me jump at ordering this Cir Pol filter but when I put it to use it's benefit was it's down fall. It's not a strong enough filter for the needs of what I bought it for. I was shooting a black car and was hoping for it to minimize the glare. In a perfect world it would remove it completely but I was expecting that. I would get in position and as I rotated the filter there was an obvious change, however it wasn't across the filter. At no point was there enough polarizing power across the horizon of the filter to take down the glare. I would get about a 20% removal to none at all then back up to the 20%. What I am left with is clean lines on the close side of the image and glare building up to the amount as if the filter wasn't even on. The KSM B&W for my 100mmL worked better but that's a long lens and I was wanting wide angles. So what's needing to happen now is an insane amount of post to correct this.
It seems like a nice idea but if you want to polarize just buy the pro-1 or better yet the KSM from b&w.
Oh, and for those of you who have never owned a circular filter before, DO NOT tighten the filter. It makes it nearly impossible to take off since the filter itself spins as you try to unscrew the filter off the lens. I have to be conscious about that every time I put this on.

Works as advertised. Totaly removes glare from water to capture any object below the water serfice. I use this filter to capture images of fish,shells, and any other object below the serfice of water. It works well on reflections off hard surfaces such as automobles. I have not yet been succesful removing glare from glass. I believe that is the nature of any polarizing filter not just this one.

This filter replaces an existing polarizer which could not properly secure my lens cap. Besides providing a secure grip on the lens cap,the high quality glass improved sharpness and clarity while removing unwanted reflections. This is not my only Hoya filter. I highly recommend this product.
