So I actually have a ton of filters from k&f concept and also the newer brand. I really like the k&f concept ones the best and I have some of their high-end filters. And I also like how they toss in the free microfiber cloths with them. These filters are all very top quality and this one is kind of a niche filter but I had to have it. I've been doing photography for about 10 years or so and I really got into the artsy side of thing and really look for a different ways to add effects and stuff to my pictures and this just brought a whole new level to my photography. This is not something that you're going to use every day and it's definitely not the most appealing kind of effect that you can put in a picture and this one really distorts only in a certain type of ways but the amount of different types of pictures that I can think to do with this are endless. Especially when it comes to doing like fashion, landscape and more. I got the one in the 67 mm because that's what the majority of almost all my filters are because they fit on my favorite lens. Overall the quality of this thing is Top Notch like all of the k&f concept ones that I've got and I super highly recommend it if you really want a quality filter that's going to last and get you those shots that you're looking for
