Camera lens neutral density filter Calumet CALSAN1655 55 mm, single-piece, black/transparent

Calumet CALSAN1655 is a single-piece 55 mm neutral density (ND) filter designed to reduce the amount of light entering a camera lens, enabling longer exposures and wider apertures in bright conditions. The filter features a black metal frame with transparent ND glass and is part of Calumet’s line of SMC Ultra Slim ND filters that use multiple coating layers to preserve image quality while providing light attenuation for creative control.

Advantages

The filter provides controlled light reduction to extend shutter speeds and allow use of larger apertures without overexposure. A multi-layer coating system (28 layers) helps maintain contrast and colour fidelity while offering surface protection. The slim profile reduces the risk of vignetting on wide-angle lenses, and the single-piece construction simplifies mounting and handling.

Suitable for

• Landscape photography requiring long exposures (waterfalls, clouds)
• Creating motion blur effects in moving subjects
• Portraits using wide apertures for shallow depth of field and bokeh
• Video work that needs controlled shutter speed and aperture in bright light

Key specifications

• Filter type: neutral density (ND)
• Effective size (thread diameter): 55 mm
• Optical design: single-piece filter with transparent ND glass
• Coating: multi-layer anti-reflective and protective coatings (28 layers)
• Frame colour: black
• Surface properties: water-repellent and scratch-resistant treatments

How to use

Attach the 55 mm Calumet ND filter to a lens with a matching thread by screwing it on until secure but not overtightened. Use live view or a tripod when composing long-exposure shots to avoid camera shake. When using wide apertures in bright light, fit the ND filter to reduce incoming light and set exposure parameters (shutter speed, aperture, ISO) according to the desired depth of field and motion rendering. Clean the filter surface with a microfibre cloth and appropriate lens cleaner to maintain image quality.

Usage recommendations

For best results on long exposures, mount the camera on a stable tripod and use a remote release or camera timer. Check for potential vignetting with ultra wide-angle lenses; if present, consider a slim-profile filter or confirm compatibility before shooting. Store the filter in a protective pouch when not in use to preserve the multi-layer coatings and surface treatments.
