Hoya HRT Filtre de polarisation et Revêtement anti-UV 77 mm

I have three of these so looking for consistency of results. They are made well and work as promised.

Took a trip to Sedona. Used this under blue sky. The polarization effect is very strong to the sky, but has very strong gradient when use at wide angle like 24mm. The effect to the mountain and tree is not that strong. Not enough to remove the reflection. I end up have to remove it. Will try under different circumstances.

The Hoya 77MM HRT Circular-Polarizer filter functions well and fit the lens on my Canon EOS 5D MkII. And produces beautiful polarized shots when I shoot landscape or cloud photography. Unfortunately, I was not aware that this lens, (for whatever reason) will not permit the Canon ultrasonic Autofocus system to function. As a consequence, I am considering returning this item and buying a genuine Canon lens of the same type, which I'm given to believe will permit AF to operate properly.

Had some great sunset shots on day one. Looking forward to more great pictures.

Great filter. Not only protects your lens, but it protects your highlights too.
