Camera accessory that tames glare and flare while adding robust filter control for mirrorless and DSLR shooters. Photographers and videographers gain confidence on bright-location shoots with the lightweight, modular K&F CONCEPT Matte Box. Is it the right addition for kit-builders who need reliable outdoor control?

⚡ At a Glance
  • Image Quality: Cleaner contrast and reduced stray light when using flags and filters
  • Best for: Landscape and run-and-gun filmmakers who shoot outdoors and use multiple filters
  • Not ideal for: Users who need a full-size studio matte box or heavy 15mm rail rigs

Mini matte box with dual 4x5.65" filter trays and adjustable carbon fibre flags. Supplied with five adapter rings and multiple mounting ports for flexible kit integration.


Cleaner shots in bright conditions - with adjustable carbon fibre flags

Top flag opens 180° while side wings extend 40°, and the side flag mounts via slots to either the matte box or the filter tray. One top knob locks the top flag and another knob tightens the lens attachment for secure positioning.

Reduced flare and improved contrast for outdoor filming, especially when the sun is near the frame. Quick flag adjustments make rapid changes between shots straightforward.

Flexible filter control - thanks to two 4x5.65" filter trays

Two 4x5.65" trays accept square or rectangular filters and include a secure locking mechanism to prevent slippage. The design supports stacking of filters for combined effects.

Stack neutral density and creative filters for exposure and look control without juggling filter holders. Film-makers can achieve graduated or stacked ND effects while keeping a tidy workflow.

Broad compatibility with common lenses and rigs - with five adapter rings and expansion ports

Included adapter rings cover 67mm, 72mm, 77mm, 82mm and 95mm lens threads, and multiple expansion ports (1/4", 3/8", cold shoe) allow attachment of accessories. Modular quick-release elements simplify mounting and future expansion.

Fits the majority of DSLR and mirrorless lenses out of the box and accepts additional accessories for matte box workflows. The kit approach reduces the need to buy separate adapters or mounts.
