Hoya Fusion Antistatic Next CIR-PL Circular polarization filter

A landscape photographer's best friend!

The main purpose of a polarizing filter is to remove reflections from, for example, water, glass and other non-metallic surfaces. A polarizing filter also deepens the color tones of the image, e.g. green is greener and the blueness of the sky is deeper, making clouds stand out whiter and clearer than usual.

In landscape photography, for example, in addition to the reflection of the water surface, the filter can be used to reduce the haze caused by the reflection of water particles in the air. Haze or sun haze causes the haze in the air. When shooting through a window, it is very easy for the rest of the landscape to be reflected off the window glass in a disturbing way. This problem can be avoided by using a polarizing filter.

The working principle of a circular polarizing filter
The filter works on the basis that when light reflects off, for example, water or a glass surface, the light becomes polarized and the polarization can be filtered out of the light using the filter. A circular polarizing filter consists of two overlapping pieces of glass, the front of which can be rotated infinitely as needed. The filter's use is affected by the direction of the surface from which the light is reflected, and the power of the polarizing filter is adjusted by rotating the front piece of glass. The effect can be monitored live in the viewfinder. The effect is strongest when the sunlight is at a 90-degree angle to the camera, and the polarization is set to its strongest.

The edge thickness of the Hoya Fusion filter is only about 5mm, which means that the risk of vignetting is generally very low, even with ultra-wide lenses.

The Hoya Fusion (also known as the EVO series in America) is an improved version of the Hoya Pro1 filter. The filter has an antistatic coating that prevents dirt from sticking to the filter. If you manage to get something on the surface of the filter, it can be easily removed by lightly wiping it with a microfiber cloth. The surface is also scratch-resistant.

When shooting through a display window, a polarizing filter prevents reflections from the window glass.
