UV MC Filter 82 mm Ultra Slim 24-Layer — Calumet

Calumet UV MC Filter 82 mm Ultra Slim 24-Layer is a multi-coated ultraviolet filter mounted in an ultra-slim 82 mm frame. It reduces UV haze and helps protect the front element of lenses from dust, moisture and minor scratches while preserving image contrast and colour neutrality. The slim profile is specifically engineered to minimise vignetting on wide-angle lenses and maintains optical performance across common landscape and travel shooting scenarios.

Advantages

The multi-coated design with 24 coating layers improves light transmission, reduces internal reflections and limits ghosting on bright light sources. The ultra-slim metal frame prevents the filter from causing dark corners on wide-angle lenses and allows for safe stacking with slim accessories. The filter provides mechanical protection of the front element without altering the lens focal characteristics or colour balance, making it suitable for everyday outdoor use.

Suitable for

• Landscape and nature photography with wide-angle lenses
• Travel and street photography where front-lens protection is needed
• Outdoor shooting in bright, hazy or high-altitude conditions to reduce UV haze
• Situations requiring a low-profile filter to avoid vignetting

Key specifications

• Filter type: Ultraviolet (UV) multi-coated
• Coatings: 24 coating layers to reduce reflections and improve transmission
• Mount diameter: 82 mm slim frame designed for wide-angle compatibility
• Frame design: Ultra-slim metal construction to minimise vignetting
• Optical effect: Reduces UV haze while preserving contrast and colour neutrality
• Primary function: Lens front-element protection against dust, moisture and minor abrasion

How to use

Screw the Calumet UV MC 82 mm Ultra Slim filter onto the front thread of a compatible 82 mm lens until it is hand-tight, ensuring the filter sits flush and is not cross-threaded. Use it during daytime outdoor shoots to reduce the effect of UV haze and to protect the lens surface; remove or replace it when using specialized filters (polarizers, graduated filters) if stacking causes vignetting or mechanical interference. Clean the filter surface with a soft blower, lens brush or microfiber cloth and appropriate lens-cleaning solution to maintain optical clarity.

Usage recommendations

For best results on wide-angle lenses, verify that the ultra-slim frame eliminates vignetting at your widest focal length before extended shoots. When combining with other front-mounted accessories, check for mechanical compatibility and test image corners to ensure the desired field of view remains unobstructed.
