Product being reviewed: K&F Concept 72mm Black Diffusion Mist Effect 1/4 & Variable ND2-32(1-5 Stops) & Circular Polarizing Filter CPL-in 1 Lens Filter with 18 Multi-Coatings for Camera Lenses (K-Series)

This polarizing filter by K&F Concept is interesting in that it's adjustable with a slider on the side of the lens to achieve different ND values. On top of that, there is another adjustment ring to fine tune the CPL. Now I'll be the first to admit that this is more advanced than I'm used to; I have a Fujifilm X-T5 and am amateur at best. That being said, it's been fun to mess around with this filter. I've had varying results on my photos; some seem no different than without the filter, and others have weird shadowed areas, I believe due to the CPL. This is a learning curve that I'm still working on. This can impact colors in your photos, so mess around with the filter a lot if you don't know what you're doing.

Some things to note when using this filter:
-No lens cap, hood, or additional filters will fit it.
-Since the adjustment slider sticks out, it's best to remove this filter before storing your camera to avoid damage.
-Takes time to adjust and dial in the right settings for your situation and not for fast shots.

The filter itself seems well made. I have mild concerns about sand or other small dust particles getting in the sliding mechanism, but no issues so far. K&F filters are usually a really good value and I think this one is as well since it does two jobs (ND and CPL). Recommended as long as you understand what you're buying.

This K&F VND filter is the do it all filter for you if you are a fan of the black pro-mist diffusion look. Having variable neutral density in combination with circular polarizer and black mist look you could essentially leave this filter on your video camera lens and get so many different looks. The large orange knob allows you to easily turn the VND portion of the filter and the rear ribbed ring allows you to turn the CPL which takes a little effort to turn but prevents accidental adjustments. The VND knob can also be tightened or loosened to adjust the tension of the VND adjustment which can be locked out to prevent accidental adjustment as well.

One problem that I ran into while using this filter was the fact that I am unable to mount this within my matte box as the protruding orange knob of the VND portion sticks out way too much and wont allow me to thread it into my matte box. You also cannot remove the orange knob by untwisting it all the way so I am just unable to use it with my matte box. Also the CPL adjustment is a little hard to adjust because unlike the VND, the CPL portion does not have a dedicated knob for you to grab onto to spin the filter.

With those gripes aside I do think this is a great run and gun filter that tries to do it all. Its perfect for someone that likes that constant black pro-mist look yet need the ability to adjust the ND and CPL. I will be using this for my fun camera as I am unable to mount this in my matte box on my FX3 but this would be perfect for my A7IV run and gun setup.

Really good quality and gives your footage a beautiful soft look. Works perfectly and fits securely on the lens.

This is fantastic. I am really enjoying having an adjustable gradient filter, rotating polarization filter, and uv filter all in one lens. The polarization filter isn't supposed to dramatically change the image, it just cuts out glare and reduces shine. So don't expect it to. If you are unfamiliar with these types of filters, do some research and learn how to use them, they will make your pictures look much better if you ise them right.

If you are ever worried about stacking filters then this the perfect filter for you because this is pretty much 3 in one. Back in my beginner days, I'd stack an adapter ring to an nd filter then put a cpl on top of that and that would create some terrible vignetting. But now that technology is better than it was before, we've got Mist Filter + CPL + VNDs in one now. Wild. For $60 this thing is not that bad. I've seen some other filter go for double the price and that's just a VND by itself or maybe even just a mist filter. So if you're starting out and you want to get better video quality or maybe even photo quality, then this is a good filter to start with. The quality still looks good and while it may not be the best for me, it's still a great filter for the money.

Perfect

Great quality for the price! Looks great and has a great feel when adjusting the ND with the lever. I use it with my iPhone 16 pro using an adapter and I have loved the increase in quality in my videos using it.

Bien arrivé. Qualité de construction et usage, surtout avec multiple filtres ND

Excellent 3 in 1 filter from K&F. I have several K&F filters and I have liked them all. This one is the first multi-purpose filter that I have owned. I love that it has the mist filter built in, because most cameras and lenses are too sharp for video. Because the VND and Mist are together, I dont have to stack filters. This means less to carry and manage when shooting. As an added inclusion, I love the little microfiber wipes they include in the individual wrapped packages. It's just a nice little extra to include.
