67mm Variable ND2-400 Filter for Phone/DSLR - Smooth Light Control

In this review the 67mm Variable ND2-400 Filter for Phone/DSLR proves itself as a flexible, well-built neutral density option for creators who need precise exposure control. The single biggest reason to buy is the true 1-10 stop adjustment that enables long exposures and shallow depth-of-field on both smartphones and DSLRs, all in a compact, lightweight kit. The reviewer found the CNC metal frame and 28-layer nano coating noticeably improve handling and image clarity compared with thin plastic adapters, making it a practical tool for landscape, urban night, and video work.

Key Features

• Adjustable ND2-400: The continuous 1-10 stop range lets photographers dial in exact light reduction for long exposures and motion blur without swapping filters.
• 28-layer nano coating: Dual-sided coating reduces glare and fingerprints while preserving color accuracy and contrast in bright conditions.
• CNC metal frame: A precision-machined aluminum frame resists loosening and offers a solid threaded connection for reliable attachment.
• Phone clip and adapter ring: Includes a universal metal phone clip and a 58mm-67mm adapter ring so the filter works with many smartphones and cameras.
• Compact kit: At about 150g with case, cloth, and adapter, the set is easy to carry for travel, hiking, or street shoots.

Who It's For

This filter set is aimed at content creators and photographers who need a single, versatile neutral density solution for both smartphone and DSLR use. It is especially useful for landscape shooters wanting dreamy water motion, urban photographers chasing light trails, and videographers who need consistent exposure when moving between light conditions.

Those who should look elsewhere are users who require specialized graduated ND filters, exact calibrated step ND sets for studio work, or users who insist on filter thread sizes other than 58mm/67mm without an available adapter. If you only shoot quick handheld phone stills in low light, the kit may be more than necessary.
