K&F CONCEPT 77mm True Color Variable Fader ND2-32 + CPL Nano-X Series filter (ND & CPL in 1)

If you shoot outdoors—especially landscapes, seascapes, or anything with reflective surfaces—light control is everything. This K&F CONCEPT 77mm True Color Variable Fader ND2-32 + CPL filter is built for one job: let you darken the scene and tame reflections without swapping filters.

On paper, it’s an efficient “two-in-one” approach: variable ND to reduce incoming light for darker skies and longer-looking exposures, plus circular polarizing (CPL) to cut unwanted glare from non-metallic surfaces like water and glass. That combo can also help boost color and contrast when conditions are bright and reflections are stealing attention.

That said, it’s not a magic wand. Variable filters can be convenient, but they still require a bit of careful handling for best results—particularly if you’re sensitive to edge effects or you’re trying to keep your framing perfectly consistent.

Key features that matter in real shooting

What stands out here is the combination of a variable ND range and CPL in one circular filter. The filter frame uses self-locking technology and rotates infinitely between 1 and 5 stops of ND reduction (ND2-32), which is meant to make it easier to dial in your exposure reduction.

It also claims to avoid the “black cross” phenomenon. If you’ve ever seen cross-shaped dark artifacts show up on some variable ND setups, that’s the kind of issue you’d rather not deal with mid-shoot. The idea is that the design keeps the filter behavior more stable as you rotate.

Then there’s the “true color” angle. The product description says it uses titanium coating technology to reduce the common problem of partial yellow or color shift that can happen with some variable ND filters. If you care about natural skin tones, realistic greens, or accurate sky gradients, that’s the part you’ll likely notice first.

What to expect from the ND + CPL pairing

Using ND and CPL together is about control. ND helps you manage brightness so your camera can hit slower shutter speeds or wider apertures where you want them. CPL, meanwhile, helps reduce reflections—think shimmering water, window glare, and glossy surfaces.

A practical example: imagine a bright afternoon by a lake. With the ND dialed to darken the scene, you can create a smoother water look. Then the CPL portion can reduce the glare so the water and sky colors appear cleaner rather than washed out. You don’t have to mount one filter, adjust, remove it, and repeat.

Still, there’s a limitation worth keeping in mind: a variable ND is “variable,” which means your results depend heavily on how you set it and how your lens renders through a rotating element. It’s convenient, but it may not match the consistency people expect from fixed ND filters for every scenario.

Build and coatings: why they’re mentioned

The filter is described as using imported AGC optical glass with 28 multi-layer coatings. The goal is high definition image quality along with waterproof and scratch-resistant characteristics.

In everyday terms, that usually matters because filters get handled, cleaned, and exposed to real weather. If you’re buying a front-of-lens accessory you plan to take outside, those coating claims are relevant—even if they can’t replace proper lens care.

Compatibility and ordering checks (don’t skip this)

This K&F CONCEPT filter is stated as compatible with all 77mm lenses, but you should still confirm the lens thread size before you order. The note says to verify the number next to the “ø” (diameter) symbol on your lens.

One more practical requirement: the listing states that an 82mm lens cap is required for this 77mm variable ND filter. That’s the kind of detail people sometimes overlook, and it can save you a headache if you already own a cap setup.

Also, packaging (old and new) will be distributed randomly with no changes to the product contents, so you shouldn’t expect the box design to match a photo you’ve seen.

The essentials for deciding if it’s worth it

If you want a single filter that can both reduce light (ND) and manage reflections (CPL), this is designed specifically for that combined purpose. It suits photographers and videographers who frequently shoot bright scenes with glare—water, glass, or reflective landscapes—where swapping filters mid-workflow is a pain.

It’s also appealing if you’ve been frustrated by typical variable ND behavior: the product specifically calls out the black cross artifact and color shift/partial yellow concerns, which are common reasons people hesitate on variable NDs in the first place.

But you may want to think twice if your style depends on ultra-critical color consistency across every setting, or if you prefer the predictability of fixed ND filters. This filter can be a strong everyday tool, but it’s not automatically the best choice for every “pixel-peeper” use case.

Pros and cons before you buy

• Pros: two functions in one circular filter (ND + CPL), variable ND control with self-locking rotation, claims to help avoid black cross artifacts, “true color” approach to reduce partial yellow/color shift, multi-layer coated AGC optical glass with waterproof and scratch-resistant messaging.
• Cons: it’s a variable ND design, so results still depend on how you dial the settings, compatibility hinges on confirming your lens thread size, you’ll need an 82mm lens cap for this 77mm filter.

Is it worth it?

Buy it if your main goal is faster shooting in bright environments where you want both exposure darkening and reflection control from one filter. It makes sense if you regularly deal with water/glass glare or you’re trying to improve sky and contrast without carrying (or mounting) multiple filter stacks.

Skip it if you already know you don’t like variable ND behavior, if you need the most predictable performance across every rotation setting, or if you’re not willing to verify thread size and cap fit before ordering. In short: it’s a practical, feature-combined filter for everyday outdoor work, but it may not replace every specialized filter in your kit.

Quick answers

Does it control reflections as well as light?

Yes. The filter is described as combining ND and CPL features to reduce unwanted reflections from non-metallic surfaces like water and glass.

What’s the ND range?

The listing states it rotates to adjust between 1 and 5 stops of ND reduction, listed as ND2-32.

Is it meant for photos and videos?

The description references both images and videos, but it doesn’t specify video-specific requirements—so treat it as a general lens filter for both uses.

What should I check before ordering?

Confirm your lens thread size is 77mm (the number next to the ø symbol), and note that an 82mm lens cap is required for this filter.

Will packaging match the product photos?

Not necessarily. Old and new packaging are distributed randomly, though the product contents should not change.
