Camera UV Filter Calumet 55 mm Ultra Slim 28-Layer SMC TG

The Calumet 55 mm Ultra Slim 28-Layer SMC TG UV filter provides lens protection and ultraviolet light reduction in a low-profile design. Sized for lenses with a 55 mm thread, this UV filter uses a 28-layer super multi-coating (SMC) combined with a TG treatment to decrease surface reflections and minimize color cast while preserving image clarity. The ultra slim frame reduces the risk of vignetting on wide-angle lenses and keeps the optical path clear while protecting the front element from dust, moisture and accidental contact.

Advantages

The 28-layer SMC TG coating improves light transmission and reduces flare and ghosting, resulting in more neutral colors and better contrast. The ultra slim metal frame minimizes mechanical vignetting on wide-angle and wide-aperture lenses. The filter provides a physical protective barrier for the front lens element against scratches, fingerprints and environmental contaminants. Threaded mounting ensures secure attachment and compatibility with accessories such as lens caps.

Suitable for

• Landscape photography where UV reduction and edge-to-edge clarity are important
• Travel and outdoor use to protect the lens from dust and moisture
• Everyday shooting on prime and zoom lenses with a 55 mm thread
• Wide-angle lenses that require a low-profile filter to avoid vignetting

Key specifications

• Filter type: UV (ultraviolet) filter
• Thread size: 55 mm
• Frame design: ultra slim low-profile frame
• Coating: 28-layer super multi-coating (SMC) with TG treatment
• Purpose: reduce UV light transmission, minimize reflections and color cast, protect front element

How to use

Screw the filter onto the front thread of a compatible 55 mm lens until it seats gently; avoid overtightening. Use the filter as a permanent protective element or attach it when shooting outdoors to reduce ultraviolet haze and protect the lens surface. Clean the filter glass with a microfiber cloth and appropriate lens cleaning solution to remove fingerprints or smudges. When stacking filters or using wide-angle lenses, confirm there is no mechanical vignetting and, if necessary, use the ultra slim side to reduce obstruction.

Usage recommendations

For best optical performance, keep the coated surfaces clean and store the filter in a protective case when not in use. When shooting in challenging light, inspect for flare or reflections and adjust hooding or shooting angle as needed to preserve contrast.
