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.

This was one of the best purchases I've made recently and I have no hesitation in recommending it, especially to travel photographers who advocate taking as little camera gear as possible. Filters are one of the accessory sets I always have with me, as they are essential for my landscape photography.

My first impression of the filters was the beautiful packaging they arrive in. They come in a hard cardboard box, with the filter itself housed in a hard plastic sleeve inside the box. The frames of all the filters, with the exception of the circular polarizing filter, are made of aluminum alloy. Although very slim in design, they certainly feel rigid without really bending, even when forced.

The glass itself on all filters is coated optical glass (to reduce reflections), which is waterproof and scratch resistant. Overall, all of the filters performed very well.

With the CPL, you can see a boost in the blue in the sky. There is a very slight vignette in the upper left corner, but it is so slight that it can be easily removed in post-production, as you can already see in my images.

The ND filter worked very well, with no color casts or vignetting. There is no unwanted X effect.

In summary, the image quality is excellent and the added benefit of using only one filter and adjusting the gradient without having to stack filters is really useful. Overall, the see, feel and last these filters are top notch, but are also affordable.

Great piece for landscape photography. Variable ND without "shadow cross", clean in both areas. Polarizing filter goes great, and if it does get too bright you'll love the ND, stepless control. Used on FZ200.

Despite a slight degradation in image sharpness, particularly at longer focal lengths, and weaker CPL performance than a standalone solution, for the relatively lower price the filter is well built, easy to rotate and performs well when it comes to Combine both ND and CPL filters without having to stack them.

I was hesitant since I've never used filters before, but this one is great. I love the fact that I can make it darker or lighter using just the rotator.
