UV Filter Calumet SMC TG 67 mm Ultra Slim 28 Layers

The Calumet SMC TG UV Filter 67 mm Ultra Slim with 28-layer multi-coating is a transparent screw-on filter designed to protect the front element of lenses with a 67 mm thread. It reduces the effect of ultraviolet light that can cause hazy or bluish casts in outdoor images and minimizes ghosting and flare through its multi-layer anti-reflective coatings. The ultra-slim frame is engineered to limit vignetting when used on wide-angle lenses while providing reliable physical protection from dust, moisture and light scratches.

Advantages

The 28-layer multi-coating improves light transmission and reduces reflections across the visible spectrum, preserving color fidelity and contrast. The ultra-slim metal frame minimizes the risk of mechanical vignetting on wide-angle optics. A precision-threaded mount ensures secure attachment to lenses with a 67 mm front thread and allows stacking with other thin filters when required. The filter offers passive protection for the lens front element without affecting autofocus or exposure metering.

Suitable for

• Landscape and outdoor photography where UV haze reduction improves clarity
• Everyday protection of the front element against dust, moisture and scratches
• Travel and street photography when a slim profile is required to avoid vignetting
• Use with wide-angle and standard prime or zoom lenses that accept 67 mm filters

Key specifications

• Filter type: UV (ultraviolet) protective filter
• Diameter: 67 mm thread size
• Frame: ultra-slim metal construction to reduce vignetting
• Coating: 28-layer multi-coating for anti-reflection and improved light transmission
• Mount: screw-in threaded mount compatible with 67 mm lens threads
• Function: reduces haze and ghosting, provides front element protection

How to use

Screw the filter onto the front thread of any lens with a 67 mm diameter until it is securely seated; avoid overtightening. The filter can remain mounted during normal use to provide continuous protection and UV reduction. For stacking multiple filters, thread additional slim filters onto the mounted filter but check for vignetting on wide-angle lenses. Clean the filter surface with a soft microfiber cloth and an appropriate lens cleaning solution to remove fingerprints, dust or smudges.

Usage recommendations

Use the filter primarily in outdoor and bright daylight conditions to reduce UV-related haze. Keep the ultra-slim profile in mind when using very wide-angle lenses; verify the absence of vignetting at the widest focal length. Store the filter in a protective case when not in use to prevent scratches and contamination.
