Neutral Density Filter lee filters Big Stopper 67mm — 10-stop light reduction

The LEE Filters Big Stopper 67mm is a screw-in neutral density (ND) filter that provides a fixed 10-stop reduction in light for long-exposure and motion-blur photography. Made to fit lenses with 67mm threads, this filter uses high-end optical glass and multilayer nano coatings to maintain image quality while reducing light intake for smooth water, streaked clouds and extended exposures even in bright conditions. The filter ships with a protective case and cleaning cloth.

Advantages

The Big Stopper delivers a consistent 10-stop light reduction in a compact screw-in form, preserving color balance and sharpness through premium optical glass and multilayer coatings. Its nano coatings improve scratch resistance and repel moisture and fingerprints, while the oversized machined-alloy outer ring provides secure attachment and easy handling in the field. The design minimizes vignetting on wide-angle lenses and is compatible with modern high-resolution sensors and lenses.

Suitable for

• Long-exposure landscape photography (smooth water, cloud movement)
• Architectural and urban scenes requiring motion blur
• Creative photography that needs very slow shutter speeds in bright light
• Lenses with 67mm filter threads

How to use

Attach the Big Stopper by screwing it into the front filter thread of a lens with a 67mm diameter. Meter or use the camera’s exposure preview to estimate the required shutter speed after applying the 10-stop reduction, then adjust ISO and aperture as needed. For best results on long exposures, use a sturdy tripod and a remote release or camera timer to avoid camera shake. Check framing and focus before mounting the filter, since strong ND filters make composing and focusing through the viewfinder or live view difficult.

Usage recommendations

Store the filter in its protective case when not in use. Clean the coated glass with the supplied cloth and avoid abrasive materials; if needed, use lens-cleaning fluid designed for coated optics. When shooting with very wide-angle lenses, verify images for vignetting and adjust composition or crop if necessary.
