love this filter. The CPL is accessed with the large ring, and the ND is accessed with the orange tabs. Finally, someone made it easy. The ND range is bracketed, of course. The CPL rotates all the way around. It also comes with a nice (leather-ish) case to protect it. Great design.

recently ordered the K&F Concept 62mm ND Lens Filter for my photography needs and have been extremely impressed with its performance. The 28 multi-coated circular polarizing and neutral density filter is a game changer, allowing me to capture high-quality images with greater control over the lighting. One of the things I love most about this lens filter is its versatility. The 2-6 stop range allows me to adjust the exposure as needed, and the polarizing effect helps to reduce reflections and increase contrast. The 62mm size is also a great fit for my lens and the multi-coated design helps to reduce any flare or ghosting. In terms of build quality, the filter is well made and feels sturdy in my hand. It's also easy to install and remove, making it a breeze to switch out as needed. The included carrying case is a nice touch and helps to keep the filter safe and protected when not in use. Overall, I am extremely satisfied with my purchase of the K&F Concept 62mm ND4-64 (2-6 Stops) ND Lens Filter Variable & CPL Polarizers Filter 2-in-1 and would highly recommend it to other photographers. It's a high-quality and versatile addition to any camera setup.

K&F knocked it out of the park with this variable ND filter. The construction is solid and the adjustment action is smooth on the filter, I have not had any issues, at all, with it. This filter is well worth the cost if you are looking for a new ND filter. Having a variable ND filter is nice on a sunny day as you can make a lot of little adjustments when trying to get shots without having to constantly be swapping filters. There is a bit of a learning curve for these, but once you get the hang of it, it can really change up the way you shoot. Most of the tutorials for these show you how you can get those smooth shots of waterfalls, however you can use these on pretty much anything and with this being adjustable, it replaces about five to ten regular ND filters. Great product at a great price.

The K&F Concept 82mm ND4-64 (2-6 Stops) ND Lens Filter Variable & CPL Polarizers Filter 2-in-1, 28 Multi-Coated Circular Polarizing and Neutral Density Camera Lens Filter: This is a super cool idea that was bound to happen sooner or later, and I’m glad K&F was the one to do it. I have come to really like their filters. I have their standard vari ND, super nice with little to no color shift, and their CP, again super well made and little to no color change. This is equally well made and comes in a similar leather filter wallet. Super high quality materials and coatings. Basically how this works is one ring controls the vari ND, and the other ring controls the CP. the CP range is greater than the ND range however, they work together to give you more ND range. It works well, and truly gives you a large range of change. The trade off is a bit of color shift here and there. I have found this to be common with almost every vari ND on the market with only a few exceptions, this rates among the better ones. I was truly impressed at how good the color rendition was on the standard vari ND. This is not a ding, it is a limitation of how they do variable ND. To find one that has no color shift is rare. If this is important to you I recommend their other model. This is a great two for one, and is very effective and well made. If you only want to throw one filter in your bag this is a great option. K&F are doing top quality work and I really like their products. This one is innovative and convenient, with a small trade off, that you may end up with from most other brands anyway. So don’t let that scare you, however it’s gonna bother you, get their other vari ND model, which is truly impressive and I would put against the best in the business. Overall I have become a big fan of this company and their quality and innovation. I recommend trying out this unique filter as well as their other filters. They are not cheap, but why would you put a cheap filter in front of you expensive lens. With glass you get what you pay for and K&F is worth the money.

love this variable ND filter. I'm using with a Canon R6 and a Canon RF 35mm F1.8 lens. Fit and finish is impeccable and and it's easy to rotate due to the tabs set at 180 degrees on the filter. Most importantly, I'm not detecting an cross-hatching, which is a common phenomenon on variable ND filters. Also, the lens cap fits securely on the filter, but you can't use a lens hood when using the filter. That isn't a big deal to me, but it's worth noting. This filter has stayed on the lens since I received it. Couldn't be happier - highly recommended. 5 stars.

If you've ever tried to stack an ND filter and a circular polarizer, you know that it is a giant pain and usually results in a dramatic dip in image quality. A useful workaround is to stack a normal and inverted polarizer on your lens to try to cross polarize the light coming in. It can work well, but can also be more of a pain to deal with than it is worth. This dual filter is an amazing combo of the two most commonly used filters - the ND and the circular polarizer. Through some sort of witchcraft, they've found a way to combine both filters into one easy to use design. You can do the circular polarize and ND filter to get those beautiful images. There is no distortion or X pattern. Color shift is minor and is on par with other high end ND filters. I like the textured rings and heavy knob for adjustments. I wish there was a way to have no ND filter as an option - so I could leave it on the lens all the time as a circular polarizer and then apply the ND as needed. It's not a huge deal, but would still be an awesome feature. Great value!

This is my first K&F product and first variable ND filter. I'm thrilled with the quality. The AR finish on the filter is flawless and the adjustment is super smooth. Having a range of ND available in a single filter is really convenient and appears even across the image.

I've picked up a number of filters from K&F lately and they have all been great, well machined, easy to adjust and fit well on my lenses. This one is no exception! As others have said, there is very little color shift with this and at all the settings you get a nice clear view with no variations in brightness across the filter. If you shoot in places that are almost always brightly lit with direct sunlight, you know that even after lowering the ISO sometimes you still can't reduce the shutter speed enough to get a nice stylistic motion blur on flowing water or waves on a beach. It can also be hard to get the iris opened up to where you get a nice depth of field blur. With this filter going all the way up to ND64 you can easily get the light low enough to take these kinds of shots. While everyone likes tack sharp photos you get with high shutter speed and high F-Stop, sometimes you just want a different look and this will let you get it. From a shallow depth of field shot to focus people on the main subject to a more motion blurred shot to give you the sensation of movement. This can also be used for recording videos. In bright light you often have to turn the shutter speed up which makes the video seem to stutter when you pan. With an ND like this you can pull the shutter speed back down again to get that more "cinematic" look to your videos. Overall a good filter that I'm really happy with. The only thing is I wish K&F was a little more consistent with their cases. Some filters come in a plastic box, others (like this one) in a little leather slip-case. Regardless of which kind of boxes you get, they really aren't marked all that well so if you carry several it's not always that easy to tell which filter is in which case without opening them and looking. But that's a small thing. All their cases are sturdy and protective as they should be.

So, I got this after watching another content creator on youtube who recommended it to help with creating that blurry background we all love, even in your studio, by cranking up your lighting and then using this filter. I'm pretty new to the whole professional camera type of thing, so I can't explain exactly why it works, but it totally does! I have a ZV E10 (I know it's not considered "professional" but to me it is!) and was struggling to get the kind of look on my youtube talking head videos that I see other people getting with the same camera. This was sort of a 'hack' I guess but it's what it's designed to do for shooting outdoors in brighter light etc. Again, I don't know the technical reasons of what is happening here, but its something to do with shutter speed. I feel terrible for leaving a review for something that I don't exactly understand, but yet, I think maybe that's helpful to know you don't need to be a camera expert to benefit from using this filter because its pretty darn simple. Love it! I feel like I have an even more professional looking shot without having to get a PHD in film school to do it.

having two filters put together in one is absolutely brilliant! and like all the other K&F concept equipment I have, the quality of this filter is also brilliant, and top notch! This is the first "combo" type filter i have ever had and it is so dang nice to use. I tend to shoot Black and White film mostly, and this filter has been extremely useful for mid day bright sunlight shooting. There is one twist ring that dials in the ND filter, and then another ring that you twist for the polarizing. And the filter is still narrow and streamlined, it is not super thick and clunky to use. I have nothing at all negative to say about this filter, it is really well built, and is easy to use and has one of the nicest protective cases i have ever seen.
