Kase Wolverine magnetic circular soft GND1.2 filter 82mm

Thanks to the magnetic ring, this S-GND1.2 soft gray gradient filter is easy to mount and remove from the lens. The filter is made of high-quality Wolverine glass, which ensures that the filter is almost indestructible.
The magnetic filter can be mounted directly on a lens with a metal housing. Is your lens not made of metal? Then you can use the supplied adapter ring to still be able to use the filter.
 

GND (Graduated Neutral Density) gray gradient filter
GND gray gradient filters have a gradation (gradient) that varies in strength and density across the surface of the glass filter. The filters are often half ND gray filter and the other half is clear. When photographing with long shutter speeds, it is important to be able to control the light. Depending on what you want to block the light from, you can place the gray gradient filter in the correct position. A GND gray gradient filter is often used together with an ND gray filter.
The gray gradient filters have different types of transitions, with different application options.
A soft edge S-GND gray gradient filter is best suited for mountainous, forested or urban environments, where the horizon does not have a flat straight transition.
A medium edge M-GND gray gradient filter can also be used in similar areas to the S-GND, but care must be taken as you need to watch out for dark lines that may appear over trees or buildings.
A hard edge H-GND gray gradient filter is best used in open areas, where there is nothing on the horizon, such as coastlines and open plains. With a hard gray gradient filter, the transition from light to dark is clear and fast and is ideal for sea and desert landscapes.
