So I just want to say right off the bat that I am a huge fan of K&f concept products. I've been doing photography for about 12 years or so and over the years I've gathered quite the plethora of photography and videography pieces of equipment and I have a lot of vintage filters that I really enjoy but for new digital stuff K&f concept are one of my favorite filters that I own. I actually have a lot of their entry level ones and also a few of their higher-end ones and this thing is absolutely phenomenal. The fit is spot on and these things slide on smooth as butter and it's very high in filter. The image clarity is amazing and the plethora of different effects that they have our top notch. Overall the functionality and ease of use of this one for the cool effects that it adds is awesome. Have gotten into doing Cinema style shots over the years and this thing is a must. The color accuracy is very spot on and also the look I'm going for is very spot on to what I'm going for. Overall 100% I say grab one of these if you're looking for a black diffusion. This filter is absolutely phenomenal. The materials they make these things out of our Top Notch and machine to perfection and the glass they use is top notch with very good Coatings and you can't really go wrong with these. They are a bit on the price of your side compared to some of the entry level stuff floating around on eBay and Amazon but they're 100% worth of money. Now if all you can afford is some of the cheaper entry level stuff I say go for that also because when I started out I only started out with some very very cheap gear and produce some very phenomenal results but just like a lot of people starting out I used to judge my own work very harshly but it made me strive to become better and better and now that I look back on some of the work I did when I started out it was actually extremely good and some of those pictures were once in a lifetime moments. Overall pretty much anything from these guys I highly recommend and if it's not too much more to save up for this it is 100% worth it
