Camera UV Filter Calumet Filtr UV MC 55 mm Ultra Slim 24 Layers

Calumet Filtr UV MC 55 mm Ultra Slim 24 Layers is a 55 mm multi-coated ultraviolet (UV) filter for interchangeable-lens camera systems. The filter has an ultra-slim profile designed to minimise vignetting on wide-angle lenses while providing protective coverage for the front element. Its 24-layer multi-coating improves light transmission and reduces internal reflections, helping to cut UV haze in outdoor scenes and preserve color fidelity under bright daylight conditions.

Advantages

The ultra-slim metal ring reduces the risk of mechanical vignetting on wide-angle lenses and maintains a low profile when used with lens hoods. Multi-coated surfaces with 24 layers lower surface reflections and ghosting, improving contrast and clarity. The glass element acts as a protective barrier against dust, moisture and scratches, extending the service life of the lens front without affecting optical performance when used correctly.

Suitable for

• Landscape and outdoor photography to reduce UV haze
• Wide-angle lenses where a slim filter profile is required
• Everyday lens protection during travel and fieldwork
• Photographers seeking improved contrast in bright daylight

Key specifications

• Filter diameter: 55 mm
• Type: Ultraviolet (UV) filter
• Mount: Screw-in circular filter
• Frame profile: Ultra slim metal ring to reduce vignetting
• Coating: 24-layer multi-coating for reduced reflections and improved transmission
• Primary functions: UV reduction, front-element protection

How to use

Screw the filter onto the front threads of a 55 mm lens until it seats firmly but without overtightening. Use the filter on bright, hazy days to reduce the effect of UV light on distant subjects and to improve overall scene clarity. Remove and store the filter in its protective case when not in use to avoid accidental scratches and contamination. Clean the glass with a microfiber cloth and appropriate lens-cleaning solution, applying gentle circular motions.

Usage recommendations

Check the lens thread size before purchase to ensure compatibility. For ultra-wide lenses, confirm that the slim profile prevents vignetting at the widest focal length. Regularly inspect and clean the filter surface to maintain optimal optical performance.
