## Summary description

Adjustable K&F Concept KF01.1402 variable neutral density (ND) filter, 62mm thread size, offering ND2 to ND400 light reduction. Constructed with Nano-C coating and HMC multi-coating, it allows long exposures and wider apertures in bright conditions, controls motion blur and depth of field, and is suited for landscape, architecture and video work.

## Long description

The K&F Concept KV34 Slim Variable ND Filter (62 mm) is an adjustable neutral density filter that reduces light transmission from ND2 to ND400. It is designed for photographers and videographers who need control over exposure in bright conditions to create long exposure effects, manage motion blur, and achieve wider apertures without overexposure.
Advantages
The filter uses optical glass with double-sided multi-layer blue coatings (Nano-C and HMC-style coatings) to preserve image quality and resist water. Its slim 7.3 mm frame and lightweight CNC metal ring minimize vignetting and reduce strain on tripods while keeping the overall accessory compact for transport. The variable density range gives flexibility for different lighting situations and creative techniques.
Suitable for
Landscape photography — long exposures of waterfalls, rivers and seascapes
Architecture and urban scenes where controlled exposure is required
Video work that needs consistent exposure and motion control
Creative photography for motion blur and shallow depth-of-field effects

How to use
Screw the 62 mm filter onto the front thread of a compatible lens. Rotate the outer ring to change the density and adjust the light reduction from ND2 up to ND400 while monitoring exposure. Use camera settings (shutter speed, aperture, ISO) or a light meter to achieve the desired long exposure or motion effect. Avoid extreme rotation positions if they cause cross-polarization artifacts; check results and refine rotation as needed.
Usage recommendations
For best results, compose and focus before attaching the filter when using very wide apertures or very long exposures. Use a sturdy tripod for long exposures and clean the coated glass with a lens-safe cloth. When shooting in bright, wet environments, the waterproof coating helps, but store the filter dry when not in use.
