I 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.

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.

For the price, this is a great quality lens. Very easy to use adjustable lens polar effect. Strong enough to use as protection for your lens. Cheap enough you're not considered about replacing

Downsizing is something I've been doing during these past few months. Everything from getting rid of complicated camera setups to clearing clutter from my bedroom on a daily basis, this is just another step.

I used to carry both CPL and ND filters, however now I find that unnecessary with accessories like this that come out. To be honest, I don't find it very convenient to carry around two filters, screw and unscrew them.

i did purchase the 82mm, which is certainly larger than needed, but with step up rings that issue is eliminated.

Overall, I absolutely recommend this because it's both a great ND filter and a great CPL filter. You don't have to compromise just because it's a combo filter!

I 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.

In short, it works very well and is a good price. Highly recommended. It is very versatile and arguably can replace several filters in your bag.

I believe they basically layer two CPL filter over each other. By doing this, you effectively get a CPL and a variable ND4-ND64 (2-6 stops) filter in one.

The operation is smooth, solid, and natural. The CPL is operated as usual by twisting the filter. The ND effect is separately operated using the orange tabs. Very easy to adjust both on the fly. The ND filter has stop markings, which helps with precision. Be sure the filter is securely attached to the lens because the filter operation is quite firm and adjusting the CPL/ND might loosen the filter from the lens if it is not secure. I appreciate the "gear teeth" grip on the filter itself for attaching to a lens. It makes it really easy grip the lens to both get it snug on the lens and also remove from the lens.

The build quality feels very good and solid. It comes in a nice looking pouch, although I would have preferred a more airtight container.

Image quality is very good. Vignetting is within normal and acceptable ranges, and it is much better than stacking two separate CPL filters or using separate CPL/ND filters.

I'm just an enthusiast, not a professional. That said, I think this is a terrific filter to keep in the bag because of the overall quality and versatility.

Not many variable ND and CPL combined filters on the market. Both VND and CPL needs to turn the filters to adjust. Sometimes you just need ND or CPL. But you still need to make sure the other function is not in the way. Also image quality degradation is a potential problem due to more layers of glasses. But it is very convenient that I can take photos of waterfall in a low shutter speed without the glare from the water. So I am prepared to take the hit on image quality while enjoying the convenience. It turns out quite acceptable. I don't see any color cast or vignetting. The rotation resistance is good on both functions.

The other feature catches my eyes is the case. It comes with a very nice leather case. You slip the filter into the case. Then, you pull an orange ribbon on the side to pull the filter out of the case. Very innovative.

Overall, this is a good quality filter from filter itself, case, to packaging. The price is quite competitive, too. You may want to give it a try.

I am obsessed with this filter. The fact that it’s an all in one just got me. I use it on my 50mm lens on my Canon R6 and my pictures turn out so crisp! I love that I don’t have to unscrew it to put a different one on — just twist and you’re good! Very impressed with this.

I 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.

The CPL+ND filter is very good for reducing the light sensitivity of the camera, making long exposure shots easier. I cannot perceive the cross shadows mentioned in some reviews at any of the filter's settings. I use the filter on a Nikon D5100. Water and glass reflections are easily removed by simply rotating the filter.
