Fotga 67mm Ultra Slim Variable ND Filter - Slim Profile ND2 to ND400

In this review the Fotga 67mm Ultra Slim Multi-Coating MC Fader variable neutral density filter is evaluated for outdoor photographers and filmmakers who want a single, compact ND solution. The bottom line: it gives a wide ND range from ND2 to ND400 in an ultra slim 6mm profile so you can use slower shutter speeds or wider apertures without heavy vignetting, and the adjustable self-locking frame with index marks makes position control straightforward during shoots.

Key Features

• Ultra slim profile: The 6mm thickness minimizes vignetting when shooting at wider angles, helping wide-angle lenses keep full frame coverage.
• Wide ND range: The variable ND covers ND2 to ND400 so one filter replaces a stack of individual NDs for motion blur and depth of field control.
• Position lock and index marks: Adjustable self-locking design and clear index marks let you set exact stops and lock at Min or Max to avoid accidental rotation.
• Optical glass quality: Made with optical glass from Japan to preserve image resolution and avoid noticeable color cast in most shooting conditions.
• Multi-coating: Super 12-layer reinforcement coating on both sides reduces flare and ghosting from reflections for cleaner highlights.
• Thread sizing: Back thread 67mm and larger front thread 72mm help reduce vignette by allowing step-up accessories on the front.

Who It's For

The Fotga variable ND is best for landscape photographers, videographers, and travel shooters who need a compact ND solution that covers a broad range of stops without changing filters. Its slim profile and multi-coating make it especially suited to wide-angle shooting where vignetting and flare matter.

It is less appropriate for users who require the absolute highest-end glass or repeatable color-critical workflows that prefer fixed single-density glass NDs; those users may prefer dedicated solid ND filters or higher-end cinema glass solutions.

Pros & Cons

Pros

• Very thin 6mm frame reduces vignetting on wide-angle lenses.
• Broad ND range (ND2 to ND400) replaces multiple fixed filters and adds creative flexibility.
• Self-locking frame and index marks give reliable positioning and repeatable stops.
• 12-layer multi-coating and Japanese optical glass help limit flare and maintain resolution.

Cons

• Variable filters can still produce some banding or uneven density in extreme settings, a general limitation of fader NDs.
• The review notes that users seeking pro-level color precision may prefer dedicated fixed NDs.

Frequently Asked Questions

Will this filter cause color cast?
Answer. The filter uses Japanese optical glass and a 12-layer multi-coating to minimize color cast, though slight shifts can occur in extreme settings; tests show it is generally neutral.

Will the slim profile prevent vignetting?
Answer. The 6mm ultra slim design reduces vignetting for wider angles, and the larger front 72mm thread further helps avoid edge darkening with many wide lenses.

How do you lock the filter position?
Answer. Rotate the exterior frame to the Min or Max tag and engage the adjustable self-lock to secure the chosen ND position and prevent accidental rotation.
