82mm True Color Variable ND2-32 (1-5 Stops) and CPL Circular Polarizing Lens Filter 2 in 1 for Camera Lens Neutral Density Polarizer Filter Nano-X Series

The cpl filter adjustment moves when you try to set the nd filter unless you hold it with your hand while rotating the other ring.

I was pleasantly surprised by the quality of this Variable ND/CPL filter! I've used a variety of screw-on VNDs in the past with mixed results, typically I would be disappointed by color casting, sharpness decrease, and/or the X-shaped vignettes that accompany VNDs. Surprisingly, the only negative artifact this VND filter showed was a bit of vignetting due to the CPL, but that's hard to avoid with any VND/CPL combination. Overall, here are my thoughts:

Pros:
- Maintains sharpness of images
- Maintains color temperature of images
- Premium build quality
- Easy-to-operate design with the aesthetic orange tab for rotating through the VND range

Cons:
- Vignetting can be noticed in the sky at high VND levels

At the moment, this might be my favorite screw-on, lightweight, "throw it in the bag" VND filter. Would definitely recommend.

Cons:

How awesome that they have combined a VND with a CPL in one filter here. How often will a photographer use both a CPL and VND shooting beach / water scenes on a bright, sunny day? Um, only all the time! I simply can't gush enough about how useful this is to have both in one filter.

I got it in 82mm to fit my Canon 24-70 f2.8 II, which has an 82mm filter ring. The threads are cleanly machined, and it works very well on this lens, and with the VND / CPL combo, I can actually shoot at f2.8 sometimes. That's pretty impressive on a bright sunny day. And even get a little motion blur. This filter is worth every penny they're asking. 5 stars.

I originally ordered a different filter that wasn't this "True Color" version, and it really threw the overall white balance off on my camera. I found myself trying to change a lot of colors to get it to look just right, but THIS true color ND filter was PERFECT! It was crystal clear and made my colors pop. I took it on a trip to Costa Rica for the last few weeks and the 1-5 stops were absolutely perfect. Whether I was filming our hikes in the jungle and experienced lower-light conditions, or whether I was filming surfing at the beach, I never needed to go any darker. I can't think of a better word than "Perfect" to describe this filter. I also love the little orange dials, they make it so easy to control. Sure, if you're constantly adjusting the outer ring for the normal ND adjustment, the polarizing ring also moves a little with it, but it's not really an issue I had any problem with. Love this.

Normally K & F products usually represent an example of a good product at a good price, but in this case they have gone one step further, and even maintaining a good price, the result is an extraordinary product.

In this model, color reproduction is excellent, avoiding the yellowing effect of other similar filters. In addition, its frame has a self-locking system that prevents the appearance of the "X" pattern when high values ​​of neutral density are used. It stands out for its absence of color casts, even in the darkest neutral density settings.

Made of premium Japanese optical glass and with 28 layers of nano coating on both sides, it effectively reduces reflections and ghosting. In addition, its hydrophobic, anti-scratch and anti-fog treatment guarantees a clear image free of imperfections.

Unlike other models, it allows you to rotate the polarizer independently of the neutral density setting, offering total control over the image.

Nice filter. Tested on a Canon 24-105 L lens. Lens cap fits fine, but the hood is a no go-either before or after applying the filter. Easy to use, good damping on the adjustments, stay where you put them, threaded on as good or better than any filter I've used. Biggest issue for me is having this with me when I need it. I expect this was designed by a waterfall guy. Can’t wait to try it when the weather breaks and I can finally get out to one. I had the best experience using a CPL when I was at Yosemite. Don't go there without one. This combo will be just the ticket when I return.

This is really cool, I used to carry some ND filters and a polarized filter, but now I got both in one unit

The adjustments are easy to make independently, but you may need to hold the ring.

The finish is good, very professional look.

"I have used filters for two demanding purposes in the past for the SLR lens: photos at high altitude in summer with a strong sun and photos of water flowing in streams to create the "flowing" effect".

However, both the lens and the filters were cheap, but now I have switched to a 100mm macro lens with a decidedly high cost, so the filters must also be of quality to support the lens itself.

This K&F filter struck me because it integrates in a single product, what I previously obtained with two separate filters, and given that as simple as it is, changing filters when changing subjects is always inconvenient.

The product arrives super protected in its leather packaging, already a sign of the importance placed by the manufacturer in preventing it from being damaged once stored with other photographic equipment.

The construction quality is immediately noticeable in comparison with previous filters: we are on another planet!
Furthermore, the filter has two handles to adjust the two internal ring nuts which are very convenient because it avoids adjusting the wrong one if you have to do so using the edge.

Let's say right away that for the test, due to rainy weather, I was not able to extend it as necessary, due to very diluted natural light.

However, I chose to photograph live sphagnum moss, because it has an intense green color that often escapes the normal lens, looking for the patch of sky in which the brightness was higher.

As you can see from the photo, on the left there is the sphagnum moss without filter with the 1:1 macro lens and on the right the same shot with the filter inserted (obviously used at maximum brightness in this case).

The colors are now significantly better.

5 star rating: barring any future updates when there will be weather that allows for a better outdoor test, I am currently fully satisfied with the filter, the price of which is adequate for a lens that costs 10 times more."

Complete in its own two-tone faux-leather case with locking magnetic lid, K&F are stepping up their game with their Nano-X line of filters.

This circular polarizer combined with a variable density filter (up to five stops) is built to the highest optical and mechanical standards. It's a first class filter with 28 layers of multi-coating to reduce flare and protect the surface. You won't be disappointed.

I have been universally happy with the 8 K&F products I have purchased so far, so I was excited to try out their True Color Variable ND CPL filter.

Like my other K&F products, the build quality is very high - probably their best yet. The filter rotates very smoothly with just the right amount of resistance to be assured it will stay where you set it. Unlike other variable NDs, this one has orange coloured tabs sticking out that make it easy to turn. It is even labelled, in very small print, to show how much ND it is set to - from 1 to 5 stops. If you are used to how NDs are named in the film production world, this variable ND goes from ND 0.3 to ND 1.5. ND 1.5 in my experience is about as high as we ever use on set.

I didn’t realize this until after a few weeks of using this filter, but the “CPL” in the product name actually refers to Circular Polarizer. This is the first and only variable ND I have ever seen that you can also use as a fully-adjustable polarizer filter as well! All variable NDs use two polarizers to darken the image, but the K&F actually lets you rotate the pola independently of the ND setting. Amazing!

This variable ND also beats any others I have used because it does not add any colour shift to your image, even at the strongest ND setting, AND it does not suffer from the black cross effect that most other VNDs give you.

At $119 Canadian dollars as I write this, it is not an inexpensive filter, but you definitely get what you pay for with optical glass. If you care about image quality, it just does not make sense to put cheap glass in front of your expensive lenses.

Very Highly recommended!
