I have and reviewed a few Neutral density filters. They are one of my favorite tools to use in landscape photography. This will be my first Variable ND experience. I'm familiar with K&F so it was a no brainer to give it try. I'm looking to improve my odds of getting dramatic skies on days that are very overcast or hazy. My camera has Aperture, ISO and shutter speed that unfortunately don't impact the hazy and overcast cloud cover situations. This filter will be a 4th way to control the light, and that by dimming select portions of the light simply by rotating the dial. When set up, we will be essentially changing the light coming from the cloud part of the frame but leaving the rest of the light details unchanged. Thats the high level view of what this does. It functions by turning an element on the front of the lens that will let you see which areas are being affected.

In Use like other K&F products, they include a sturdy case to keep the optics fingerprint and smudge free. This particular kit includes 3 free microfiber cleaning cloths, individually wrapped. The few days I went out with this it was cloudy but not hazy or overcast. Still, the filter brought out more detail in the clouds and made them a tad less exposed Improving the overall shot. I will continue to use these confident that under the overcast skies I'm going to bring out more cloud sharpness and definition and cut through the haze. So Far so good.
