43mm Variable ND Filter for Light Control

The Urth 43mm Circular Variable ND64-1000 filter provides adjustable light reduction from 6 to 10 stops. It fits lenses with a 43mm thread diameter. Photographers use it to manage exposure in bright conditions without changing aperture or shutter speed settings. It suits both amateur and professional users seeking precise density control.

German SCHOTT B270 Glass with 20-Layer Nano-Coating

The filter uses German SCHOTT B270 optical glass for maximum light transmission and a consistent transmission curve. A 20-layer nano-coating repels water, oil and scratches while making cleaning easier. The ultra-slim rim prevents vignetting on wide-angle lenses. Double threading allows stacking additional filters or attaching screw-mount lens caps.

6 to 10 Stop Density Range Decides Suitability

The adjustable 6 to 10 stop range determines whether this filter matches the required light reduction. Buyers needing less than 6 stops or more than 10 stops of neutral density should select a different filter density. The 43mm thread size must match the lens filter thread exactly for proper fit.

Questions about this item

Will the 20-layer nano-coating on the German SCHOTT B270 glass wear off and need replacement?

The 20-layer nano-coating protects the German SCHOTT B270 glass from water, oil and scratches while making cleaning easier; it is a permanent surface treatment and does not require replacement under normal use.

At which f-stop setting does vignetting first appear on wide-angle lenses?

The ultra-slim rim is designed to prevent vignetting across the full 6 to 10 f-stop range, even on wide-angle lenses.

Does the double-threaded mount trap heat during long exposures in bright light?

The double-threaded design is a mechanical feature for stacking filters or attaching screw-mount caps; it does not affect heat dissipation, and the filter itself adds no active heat during all-day use.
