Heliopan

77mm Slim Circular Polariser

CPL Filter

This 77mm Slim Circular Polarising Filter from Heliopan is primarily designed to eliminate polarised light, producing increased colour saturation. This is particularly noticeable when photographing outdoor scenes, where a CPL filter will work to combat atmospheric fog to deepen the blue of the sky, highlight white clouds, and eliminate reflected light bringing detail back in to reflective surfaces such as water or glass.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. They also help to protect the filter substrate and keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and colour fidelity. It will not affect picture colour and uses a slim brass filter ring that does not have front threads, to avoid vignetting when used with most wide angle lenses. All filters will also offer a degree of protection for the front element of your lens against moisture, dust and scratching.
