Review on 📷 K&F Concept 77mm ND1000 Filter: Ultra-thin, Waterproof 10-Stop ND Lens Filter with HD Glass Coatings for Camera Lens by David Crawford

Update 2/9/2020 I bought a 67mm lens before my project because I thought it would be just as good as my 72mm lens. IDK why am I not allowed to write a review for 67mm so I have to write it above this review. So please don't confuse. I definitely give 72mm 5 stars. 67 mm 1 star. Terribly terrible vignetting. So frustrated that I trusted the company and bought it early and now my returns window is closed. The vignetting is too strong, and there was also a spot inside the filter glass. I've tried everything and to no avail. So disappointed. I DO NOT RECOMMEND THIS TO ANYONE! If you are on a budget this is a great ND filter. Does its job and doesn't give off too much of the vignetting or X that others seem to get with other ND filters. Love the packaging it comes in as well as the protective case that comes with it. Honestly, for such a price I didn't just expect amazing quality. I recommend it to any photographer who is not yet ready to spend big money on ND filters.
