Review on K&F Concept 77mm ND8 (3-Stop Fixed Neutral Density Filter) ND Lens Filter - Premium 28-Coating HD Hydrophobic Ultra Slim Nano-X Series Filter for Camera Lens by Jay Arnold

As a photographer, I try very hard to use reliable equipment. K&F has done a great job establishing itself as a reliable and affordable camera company. I own some of their other gear and continue to be impressed by their commitment to superior build quality and attention to detail in their products. I found that the filter screwed directly onto my lens with ease, and I was also able to remove it with ease. Unfortunately I couldn't do a long exposure because I don't live near waterfalls and when I got this filter the weather didn't really help me much. However, I brought the filter up to the lens without screwing it onto the lens to see the difference between the image with and without the filter. With this type of test, you can clearly see a correctly exposed image and a slightly darkened image, so only the "hot" spots of light can be seen in the photo. I took a few shots with the filter in place and found that there were no issues with vignetting around the edges and as the glass is high quality I didn't notice any ghosting either. Overall, this is a really good option for a budget ND lens filter.
