I run K&N air filter in almost all of my vehicles and Amazon was the best price on the filter for my F150.

I put something on all my outdoor lenses to protect them, and I like to use a UV filter to cut a little of the normal haze shooting in beachlike settings. I usually use something pricier, but decided to try the K&F Concept 52mm MC UV Protection Filter.It arrived in a slightly wider than normal filter box. The box was slightly larger because the filter was packed in a latching plastic box with foam protecting the filter from damage. I looked at the filter under a magnifying light, and it was flat and smooth with no scratches or oddities. It fit my 45-150mm lens perfectly, and it really is a low profile filter. It doesn't seem to affect lens sharpness, doesn't affect clarity, and I'm pleased with it.I'm quite happy with this UV filter. Is this filter as good quality as one of my $50 B+Ws? Possibly not, but on the other hand, the B+Ws cost over twice as much, and you'd have to be a pixel peeper to notice the difference in image quality. Viewing my pics at 100%, I'm satisfied.

I gave this K&F Concept 72mm Black Diffusion filter a try to see what type of effect it would have compared to a UV filter. This filter gives a slight cinematic effect and makes photos and video softer and fuzzier. There isn't a huge difference, but you can certainly tell a difference when shooting people.It makes the skin a bit softer and smoother and backgrounds are not tack sharp. The pic shows it was a little dirty out of the box, but the graininess in the glass is supposed to be there to give photos the soft effect.Overall, this is a nice filter to have in your camera bag, especially if you shoot portraits or want a soft effect with video.

As you can see from the Amazon page, this graduated neutral density filter is really great for sunsets. The sky is relatively bright, the foreground somewhat dark. Without a filter, the meter measures the light of the sun and the dark areas are washed out. With a solid neutral density filter, the foreground is too dark. A graduated neutral density filter blocks some of the sunlight but allows the foreground to appear normal. This graduated lens makes a huge difference. It dramatically improves pictures of sunlight. It is also good to block out glare, though I would use a polarizer for that. One problem with photography is that most photographers fall into one of two categories: they are either pros or amateurs. The pros want the best equipment and their livelihood depends on their having it. The amateurs want their cameras to do everything for them. There are excellent filters for the former, and the latter mostly don't know what a filter is. That leaves occasional photographers like me often out of luck. I don't want to pay lots of money for something that I will rarely use. K+F Concept is a good solution. It's good quality at a relatively reasonable price--or at least a price serious hobbyists would consider paying. I suspect that a comparable filter from B+W is better, but I'm not willing to pay 2-3 times the price of a K+F to find out. I love shooting in sunset conditions. So, I am very happy with this filter.

I feel like all adjustable filters should come with a putter like the one that comes with this variable ND filter. I have a few K&F concept ND filters already, but this one is by far my favorite.As usual, the optical quality of the filter is excellent - there's no color shift, and the tint is even and consistent throughout the frame with no hotspots. The entire range provides a very good spread of stops from 1.5 through 1000.There's a hard stop at both ends of the putter range to stop you from going beyond the stops. As a result there's no "X" or aberrant pattern. Just crisp, even, density.Filter threaded onto my lens smoothly and effortlessly. No binding.The putter is obviously a major selling point, at least for me.Comes in a nice little storage case that offers plenty of protection for the filter while you're not using it.Great filter through and through.RECOMMENDED>

I'm a professional videographer and I bought this filter for my Canon 24-105 F4 L lens. I have to say that I'm VERY impressed with the construction and performance of this filter. It's wonderful to now be able to shoot live video, outside in the desert, at F8 instead of F22. It also seems that the image quality is modestly improved. Thank you!Robert Marcos

Fits my 3.3 v6 2018 F150 perfectly! K&N said it was the one... Amazon needs to update the fitment guide. An amazing difference in just a new air filter! Just ordered a K&N for the Jeep!

I'm really happy that this filter can be screwed onto my Nikkor Z 24-70 f/4 S with the lens hood in place. Obviously I need to reach into the lens hood to adjust the filter, but that's ok. No vignetting that I can see.The filter works great, nice smooth action and a great range of density.
