Checked all my boxes and did not disappoint me. I am happy I spent a little more to get this unit.

The material is delivered very well packed, in several very nice boxes. The rings and filter guard are made of metal of good material. The filter is made of glass. I was only able to take a picture at home and reduce the light to 10 levels, as the manufacturer says. You can see that everything is of quality. I will go out and comment on the quality of the filter. I recommend it to anyone. Very happy so far. I will buy more filters from them in the future.

Great filter for night street photography in well-lit situations. Street signs, lights, etc. Give your pictures a very nice, soft glow. During the day it gives a soft, cinematic touch. Not 100% on my lens but a very nice filter to have in your bag.

This ¼ Black Diffusion Filter from K&F is a very high quality optical filter that gives your photos a subtle but noticeable softening and renders skin tones with a beautiful softness that doesn't look artificial. Highlights have a soft glow/bloom and the overall contrast is slightly reduced. Unfortunately, there is no industry standard for exactly how much diffusion a ⅛, ¼, ½ filter should add to the image, so each manufacturer is free to choose how much diffusion to add to each filter in their line. I like how much diffusion K&F put into this filter, unlike other manufacturers whose ¼ diffusion filters use too much diffusion. Another quality indicator are the plastic boxes that K&F encloses with its filters. They are superior to boxes from other companies and are pleasant to use. I have two different types of boxes from K&F and they are both excellent.

It's a good backpack. Quality, well designed and well distributed. Two things strike me: firstly, how comfortable it is (and it's not the first urban backpack I've had) and secondly, despite the fact that it's very sensible, its capacity is excellent. I usually carry all my things in cardboard boxes, in metal or plastic boxes so that they don't get scattered around me, and the truth is, I was very surprised: when I received it and saw it for the first time, I didn't think so it would fit whatever I put in it and there's still room left. And all of this without the backpack deforming or losing its design. I walk around the city a lot - and I take a cane with me because I have difficulty walking - and the truth is that my backpack doesn't bother me or weigh me down. When it comes to security... Well, the little thing with the numerical code lock is very good, but the backpack cannot withstand the "knife" that criminals in Barcelona (Spain) are so fond of. However, backpacks that can withstand this are much more expensive and pay more attention to durability than to interior and exterior design: I prefer this one and take the risk. The front pocket is very useful for carrying the inevitable papers that you end up having to carry with you no matter how digital you want to live. It's nice to be able to access it without having to open the backpack and crawl inside. The fact that it can be separated from the set may be funny, but it doesn't make me feel cold or hot. In the months I've carried my backpack I haven't unplugged it and I don't think I will, except perhaps on a very sporadic occasion. In short, a highly recommended product with good value for money. There are of course much better backpacks (and beware that it's difficult), but if you want them, prepare your wallet.

It was a gift, my grandson was delighted, he ticked all the boxes!

Amazing filter for night street photography in nicely lit situations. Street signs, lights, etc. Add a very nice soft glow to your images. During the day, it's add a soft cinematic touch.

Not on my lens 100% of the time but a very nice filter to have in your bag.
