Polarizing filter is the right way to make impressive outdoor photos in sunlight. The colours will be perfectly balanced throughout the slide including the beautifully blue sky.
The Hoya HD Nano 82mm polarising filter is necessary for outdoor sun photography. The filter suppresses haze and increases the saturation and vividness of colours so that a clear sky will have the right shades of blue in your photos. This filter has a 25% higher light transmission than standard polarizing filters and while it polarises the light to remove reflections and increase colour saturation, it does not affect the colour balance of images.
The filter protects the lens from physical damage and repels water and grease. It is made up not only of hardened glass but also an ultra-hard coating that protects your lens under even the most severe conditions. The very hard coating can last up to 200% longer than conventional coatings. The lens is packaged in a very thin frame that has a front thread to connect other filters or lens caps.
