LEE Filters Big Stopper ND Filter (100 x 100mm, 10-Stop)

The LEE Filters Big Stopper 100 x 100mm ND Filter is a professional neutral density filter designed to give photographers greater creative control over exposure and motion. Featuring a 10-stop light reduction with a 3.0 optical density, this filter significantly reduces the amount of light entering the lens, allowing photographers to achieve longer exposures and wider apertures even in bright lighting conditions.

Ideal for landscape, architectural, and fine art photography, the Big Stopper makes it possible to capture dramatic long-exposure effects that would otherwise be difficult to achieve in daylight. By extending shutter speeds, photographers can transform moving water into smooth, flowing textures, create soft cloud movement, and introduce artistic motion blur while maintaining proper exposure.

The filter also allows photographers to use wider apertures in bright environments, providing additional control over depth of field and background separation. Its uniform neutral density design darkens the entire image, making it a versatile creative tool for balancing exposure without introducing graduated darkening across the frame.

Constructed from high-quality optical glass, the Big Stopper is designed to maintain image clarity and detail while delivering substantial light reduction. Its precision-crafted construction supports high-resolution photography, making it a dependable addition to professional and enthusiast camera kits.

Measuring 3.9 x 3.9" (100 x 100mm), the filter is compatible with the LEE Filters 100mm Filter System, which supports a wide range of camera and lens configurations when paired with the appropriate holder and adapter ring. Combining powerful light reduction, optical glass construction, and creative exposure flexibility, the LEE Filters Big Stopper is an essential accessory for photographers looking to capture dramatic long-exposure imagery.
