  • Ultra-slim rim prevents vignetting on wide angles
  • Double-threaded design allows stacking or lens cap use

46mm Variable ND64-1000 Filter

This 46mm circular variable neutral density filter provides adjustable light reduction from 6 to 10 stops. It suits photographers and videographers who need flexible exposure control in bright conditions. The variable density allows wider apertures for shallow depth of field or slower shutter speeds for motion blur without overexposure. It threads directly onto compatible 46mm lens fronts.

6 to 10-Stop Range and German SCHOTT B270 Glass

The filter covers a 64 to 1000 density factor, handling bright daylight through to very intense light where heavy reduction is needed. At the extremes of the range, colour casts or cross-polarisation artefacts may appear, which is typical for variable ND designs. German SCHOTT B270 optical glass is used for clarity. The 20-layer nano-coating maintains consistent transmission across the range.

Ultra-Slim Double-Threaded Rim and Nano-Coating

An ultra-slim rim minimises vignetting on wide-angle lenses, preserving the full frame. Double threading allows stacking additional filters or mounting a standard 46mm lens cap on the front. The 20-layer nano-coating repels water and oil while resisting scratches, making the glass easier to clean in the field. This construction supports faster workflow outdoors.

Questions about this item

Will the 46mm filter thread fit my existing 46mm lens without vignetting on wide angles?

The ultra-slim rim is designed to avoid vignetting, so it should work cleanly on wide-angle lenses that accept 46mm threads.

How can I verify the 20-layer nano-coating is performing after I mount the filter?

Check for consistent 6 to 10-stop light reduction across the frame and inspect for flare or colour shift in bright highlights; the coating also repels water and oil for easier cleaning.

Does the double-threaded design let me stack a 46mm circular polariser or lens cap on the front?

Yes, the front thread accepts standard 46mm accessories such as a circular polariser or protective cap, while the rear thread mounts to your lens.
