K&F Concept 67mm Clip-on Variable ND2-32 Phone Lens Filter Kit

In this review the K&F Concept 67mm clip-on ND2-32 filter kit is judged as a practical, budget-friendly way to get DSLR-style control from a smartphone. It is best for photographers who want to shoot long exposures or shallow depth of field on the go without changing cameras. The single biggest reason to buy is the variable neutral density element that delivers up to 1-5 stops of light reduction while preserving natural color, making it useful for travel, landscape, time-lapse and social media work.

Key Features

• Variable ND2-32: Lets the user dial from 1 to 5 stops of light reduction to slow shutter speeds or open apertures for motion blur and background separation.
• 67mm Nano-K optical glass: Premium optical glass is designed to maintain accurate color and image integrity while reducing unwanted artifacts.
• 18-layer MRC coating: Multi-resistant coating cuts reflections and glare to preserve contrast in bright conditions and high-contrast scenes.
• Universal clip-on design: The supplied clip clamps over most smartphones and even works with many phone cases so you can shoot without swapping lenses.
• Also fits DSLR lenses: The 67mm threaded filter can be used on cameras or adapters with a 67mm thread for flexible multi-device use.

Who It's For

This kit is aimed at hobbyist photographers, travel shooters, and content creators who want greater exposure control from a phone without learning complex adapters. It is especially good for people shooting daytime long exposures of waterfalls, urban traffic trails, or achieving shallower-looking phone portraits for Instagram and weddings.

It is less suited to strict professional workflows that require calibrated, variable ND performance under demanding studio conditions or for users who need integrated multi-accessory mounts; those users should consider dedicated camera filters and adapters. Casual users who never change shutter speed or aperture may find the accessory unnecessary.

Pros & Cons

Pros

• Effective variable density range for creative long exposures and motion effects.
• Optical glass and 18-layer coating help keep colors natural and reduce flare.
• Clip-on system is quick to install and works with many phone cases for convenience.

Cons

• Some users report mixed ease of use when aligning the clip and operating phone camera controls during a shoot.
