Neutral density camera filter 55 mm Calumet CALSAN0855 — 55 mm filter size

The Calumet neutral density camera filter CALSAN0855 is a 55 mm screw-in ND filter designed to reduce the amount of light entering the lens, allowing longer exposures or wider apertures in bright conditions. This single-piece filter features an ultra-slim profile and a multi-coated optical surface with 28 coating layers to preserve image quality while providing effective lens protection. The filter is suitable for lenses with a 55 mm filter thread and is available in a subtly finished black/transparent design.

Advantages

The CALSAN0855 ND filter provides reliable exposure control by reducing incoming light without altering color balance, enabling longer shutter speeds and fuller control over depth of field. Its 28-layer multi-coating minimizes reflections, ghosting and flare to maintain contrast and sharpness. The ultra-slim construction reduces the risk of vignetting on wide-angle lenses, and the coated surface adds water-repellent and scratch-resistant properties for everyday use and easier cleaning.

Suitable for

• Landscape photography — long exposures to smooth water and clouds
• Portraits in bright light — using wide apertures for shallow depth of field
• Motion blur effects — capturing movement in traffic, people or flowing water
• Outdoor video — maintaining proper shutter speed and cinematic motion blur
• High-contrast scenes — preventing overexposure in snow or sunny conditions

How to use

Screw the CALSAN0855 filter onto the front thread of a lens with a 55 mm diameter until it is secure but not overtightened. Compose and focus your image before making long exposures, or set the desired aperture when aiming for shallow depth of field. When using very long shutter speeds, use a sturdy tripod and remote release or camera timer to avoid camera shake. Check live view or a test frame to ensure exposure and composition are correct, and adjust ISO, aperture or shutter speed as needed.

Usage recommendations

For best results, combine the CALSAN0855 ND filter with a tripod and cable release for exposures longer than one second. Clean the multi-coated surface with a microfiber cloth and appropriate lens cleaner to preserve coatings. Avoid excessive force when attaching or removing the filter to protect the lens thread and the filter frame.
