The Fotodiox 53mm WonderPana Go Circular Polarizer Filter is designed for use with the GoTough WonderPana Go Filter Adapter System for the GoPro HERO3 digital camera. It helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage. This filter also includes a plastic storage box with cushion liner.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

A: Hi Jeff, you mean the black shade in a picture, if I take this between 12-16mm wide angle, right? It depends to the angle of the sunlight and in which angle I take that image. Usually it is not possible to adjust it in advance if you need to take that pic with 12mm wide angle.Bad luck...Best regards Vedat

Q: 8. 1. Can this circ-polarizer be stacked with a wonder-pana solid ND filter? e.g. using both polariser and ND-8 filter (or ND-32 filter) together? 2. If they can be stacked, will vignetting be observed on the Nikon 14-24 with two circular filters stacked? 3. Can we stack a circular wonderpana 145 filter with their rectangular 66 graduated ND filters? 4. If we can stack a circular with rectangular GND, will vignetting be observed on the Nikon 14-24 with total 2 filters (1 circular and 1 rectangular)?Thank you!
