K&F Concept Nano-X magnetic filter kit CPL, variable ND2–ND32 and Black Mist 1/4 with adapter ring and cap 77 mm

Nano-X magnetic CPL, ND2–ND32 and Black Mist 1/4 filter kit, 77 mm. The set saves hunting for single pieces: the filters match in size and mounting and take little room in the bag, so they are at hand whenever the light changes.

• 28 anti-reflective layers
• Magnetic mount — on and off in a second
• The surface repels water and grease and resists scratches

Several filters in one pack

The set brings together the filters most often used with this kit, so they need not be bought one at a time and all mount the same way. Exactly what is included is listed below. The filters can be used individually, depending on what the scene calls for.

Magnetic mount

The filter goes on magnetically — a magnetic adapter ring screws onto the lens and the filter holds itself on. A swap takes a second and nothing has to be screwed.

The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field.

The polarising and variable ND filters snap together and work as a single 2-in-1 filter: with the knob locked, turning the front glass sets ND2 to ND32; with the knob released, turning the rear glass controls the polarisation. The Black Mist 1/4 filter goes on top, so one kit gives five combinations — CPL, Black Mist, CPL with ND, CPL with Black Mist and all three at once.

A magnetic lens cap is included. It holds on the filter by itself and comes off in one move, and when the filter is not fitted it can also be screwed straight onto the lens thread.
