The 58mm 7artisans ND Filter 58mm 1-Stop Graduated Photoelectricfrom 7artisans ND Filter 58mm 1-Stop Graduated Photoelectricallows you to balance exposure. The filter has the strongest effect/heaviest density at the outer edge of the filter, lessening-to-no ND effects at the center of the filter. This rotatable filter allows you to mount the filter on your lens and then align the graduation effect so you can photograph scenes with large bright areas, such as the sky, to achieve better cloud detail and color saturation, while maintaining proper exposure for your subject. Made of optical glass, each side of this glass features a waterproof, scratch-resistant, and oilproof coating, and the glass is polished to be flat on both sides so you can use it on wide-angle to telephoto lenses.

The filter is made of ultra-slim aviation aluminum glass with a non-slip CNC design. It easily installs on the lens with no vignetting or dark corners, even on wide-angle and telephoto lens.

The GND places the most density at the edge of the filter and tapers to clear by the center of the filter in order to accommodate photographing scenes with large, bright areas such as daytime sky.

With the GND, you can bring the picture to an exposure balance where you can avoid situations where the sky is too white, or the ground is too gray.

You can rotate the GND filter to achieve the appropriate effect. The front frame is threaded for use with multiple hoods, caps, and filters.

The Graduated Neutral Density (GND) Filter helps manage the lighting condition during golden hours, balancing the light between ground and sky to achieve better cloud detail and color saturation.

Both sides of the glass with double side polishing technology ensures high-quality images even on the telephoto lens. The gradient coating technology ensures uniform color and accurate stop-dimming without deviation.

This GND filter is made of optical glass. Each side of the glass is waterproof, scratch resistant, and oilproof. This makes it easy for cleaning and carrying and is suitable for all adventures.
