K&F CONCEPT 67mm True Color Variable Fader ND2-32 + CPL Nano-X circular filter (ND & CPL in 1)
Product description
If you’re trying to smooth out motion, tame harsh light, and cut glare without swapping filters all day, this K&F CONCEPT 67mm Variable Fader ND2-32 + CPL in 1 is built for that exact workflow. It combines neutral density (ND) control with circular polarizing (CPL) behavior in one ring, so you can darken the scene while also dialing down unwanted reflections from non-metal surfaces like water or glass.
But like most “two-in-one” ideas, it’s not magic: it’s excellent when you want convenience and consistency, and it can be a bit limiting if you prefer a very specific look or you’re picky about fine tuning. Still, for travel, landscape, and everyday shooting, it’s the kind of filter that earns its keep.
The essentials (what it does for your photos and video)
This filter is designed to help you manage how much light hits your lens. By using the variable ND range labeled ND2-32, you can reduce light to darken scenes when conditions are bright—useful for things like slowing shutter speeds for smoother water or clouds.
At the same time, the “CPL” aspect targets reflections. That means you’re not only controlling exposure, you’re also reducing glare and improving contrast where reflections normally wash out detail (think water highlights, wet rocks, and glass reflections).
The manufacturer also positions it as a “true color” variable ND, addressing a common complaint with variable ND filters: partial yellowing or color shift. If color fidelity is one of your main concerns, that’s the promise to focus on.
What stands out in real shooting
The variable control is handled by a rotating system with self-locking technology. It rotates infinitely between 1 and 5 stops (within the ND2-32 range). That matters because you’re not just choosing a single fixed strength—you’re adjusting to what the scene needs.
There’s also a practical detail: the filter is described as avoiding the “black cross” phenomenon. If you’ve ever seen that cross pattern appear with certain variable filters at awkward positions, it’s one of those issues you’ll appreciate not having to fight.
On the optical side, it uses imported AGC optical glass and includes 28 multi-layer coatings, described as waterproof and scratch-resistant. That suggests a focus on durability and maintaining image sharpness, not just gimmicks.
Key points to consider before you buy
First, you need to match the filter size to your lens threads. This model is for 67mm lenses, and the listing specifically notes that you should verify the lens thread size before ordering.
Second, there’s a compatibility detail that’s easy to miss: it states that a 72mm lens cap is required for this 67mm variable ND filter. That doesn’t make it unusable, but it’s the kind of small “setup cost” that can be annoying if you already own a specific cap.
Third, variable ND + CPL in one ring is convenient, but it’s also a compromise compared to using separate ND and CPL filters. If you often shoot in situations where you want very independent control (and possibly different filter stacks), you may find a two-filter approach more flexible. This one suits people who want fewer parts to manage.

Where it shines, and who should skip it
It’s a solid pick if you want one filter that can both reduce light and manage reflections, especially for landscape and outdoor shooting. It also makes sense if you’re buying for travel—fewer filters to pack, fewer filter swaps mid-session.
You may want to skip it if you already prefer using separate filters (ND and CPL) for maximum control, or if your workflow requires a very specific adjustment style that’s easier with independent rings. Also, because this is an “in one” design, it’s worth knowing it’s built for convenience more than specialization.
A practical example: you’re shooting bright daylight by the water. With this filter, you can rotate to darken the scene for more dramatic exposure, then adjust to reduce glare so the water and nearby surfaces keep more usable contrast instead of turning into bright reflective patches.
Final verdict
It’s worth considering if you want a variable ND that’s aimed at true-color behavior, plus CPL-style reflection control, all in a single 67mm filter. The rotating 1–5 stops approach, the “no black cross” claim, and the emphasis on color shift reduction are the reasons this one stands out on paper.
It might not be the best choice if you’re the type of shooter who regularly relies on separate ND and CPL filters for independent, highly customized control—or if the lens-cap requirement (72mm cap for a 67mm filter) would annoy you.
Mini FAQ
How do I know if this will fit my camera lens?
It’s designed for 67mm lenses. Check your lens thread size (the diameter number next to the ø symbol) before ordering.
Does it help with reflections from water and glass?
Yes—this filter is described as using ND and CPL features to avoid unwanted reflections from non-metallic surfaces like water and glass.
What’s the ND range on this filter?
The listing describes a variable range labeled ND2-32, with rotation between 1 and 5 stops.
Will this create a black cross effect?
The product description says it avoids the phenomenon of producing black crosses, thanks to its self-locking rotating design.
Is this filter meant for true color?
The listing specifically mentions titanium coating technology intended to reduce partial yellow and color shift, aiming for true colors in photos and videos.
