K&F CONCEPT KF01.1087 77mm ND2-32 ND & CPL Filter

ND2-32: The K&F CONCEPT KF01.1087 Nano-X Series combines variable neutral-density adjustment and circular polarisation in one 77mm lens filter. It is aimed at photographers wanting light control and reduced reflections without stacking separate filters, though customer feedback notes possible vignetting at maximum ND settings and mixed colour results.

At a glance

Combines variable ND adjustment with a circular polariser to control incoming light and reduce reflections from non-metallic surfaces such as water and glass.
The listing describes five frame marks from Min to ND32 for selecting ND positions.
The seller claims the design avoids the X-shaped cross issue associated with variable ND filters, including on wide-angle lenses.

What to know before buying

Listing details to confirm

The listing has inconsistent compatibility and size details: it identifies this as a 77mm filter for 77mm threads, but another feature claims compatibility with 40.5mm lenses and says a 95mm filter needs a 112mm lens cap. Confirm the selected filter's thread size and cap fit before buying. The listed 2-inch screen size, manual exposure control and maximum shutter speed are also not clearly applicable to a lens filter. The package version may vary, according to the listing, which says the product itself is unchanged.

Who is it for?

A good fit for

Photographers with a lens that has a 77mm filter thread who want ND and polarising effects in one filter.
Outdoor photographers seeking to manage bright light and reflections from water or glass.

Less suited to

Owners of lenses without a 77mm filter thread unless they have a suitable, separately confirmed adapter.
Photographers who require assured vignetting-free results at the highest ND settings or predictable colour across all conditions.

Customer feedback is generally favourable about perceived quality and functionality, with reports of useful reflection control and good fit in some cases. Experiences are mixed on colour accuracy, reflections, value and fit, and feedback mentions vignetting at maximum ND settings and a lens-cap compatibility issue. These reports matter most for buyers relying on the filter's combined ND and CPL effects at stronger settings. Aggregate ratings are mostly in the higher categories, but do not establish how it will perform with a particular lens or shooting setup.

Positive themes

Customers describe the filter as good quality and functional.

Mixed feedback

Feedback on reflection control and colour accuracy is mixed.
Some customers report vignetting at maximum ND settings, a lens-cap compatibility issue, or disagreement about value.

Frequently asked questions

What does this filter combine?

The listing describes variable neutral-density and circular polarising effects in one filter. It claims the ND effect controls incoming light and the polariser reduces reflections from non-metallic surfaces.

Will it fit my camera lens?

The product title and compatibility details specify a 77mm filter thread. Check the diameter marked on your lens, since another listing feature gives conflicting size information.

Can vignetting or colour changes occur?

Customer feedback is mixed on colour accuracy and mentions vignetting at maximum ND settings. The listing claims no X-shaped cross and no colour shift, but these are manufacturer claims rather than independently verified results.
