UV filter Calumet SMC TG 82 mm Ultra Slim 28 Layers

The Calumet SMC TG 82 mm Ultra Slim 28 Layers UV filter is a slim-profile photographic filter designed to protect 82 mm threaded camera lenses from ultraviolet light and everyday wear. The filter’s 28-layer multi-coating minimizes reflections and flare while preserving contrast and color fidelity, making it suitable for outdoor photography where haze or UV cast can reduce image clarity. Its ultra-slim frame reduces the risk of vignetting on wide-angle lenses while providing continuous protection against dust, moisture and accidental contact.

Advantages

The 28-layer SMC (super multi-coated) treatment suppresses surface reflections and ghosting, improving light transmission and image clarity. The ultra-slim filter ring is engineered to limit vignetting on wide-angle lenses and to sit unobtrusively on lenses with 82 mm thread. As a UV filter it acts as a protective barrier against scratches, fingerprints and light physical impacts without altering the lens’s optical performance.

Suitable for

• Outdoor landscape and travel photography where UV reduction and haze control are needed
• Everyday lens protection for photographers who keep filters mounted permanently
• Wide-angle lenses with 82 mm filter thread where a slim profile is required to avoid vignetting
• Situations requiring reduced flare and improved contrast, such as backlit scenes

Key specifications

• Filter type: Ultraviolet (UV) protective filter
• Mount size: 82 mm screw thread
• Coating: 28-layer multi-coating to reduce reflections and increase light transmission
• Frame design: Ultra slim profile to minimize vignetting on wide-angle lenses
• Primary functions: UV reduction, haze control, physical protection of the front element

How to use

Screw the filter gently onto the front thread of an 82 mm lens until it is snug; avoid over-tightening. Use the filter during outdoor shoots to reduce UV-related haze and when you want to keep the front element protected during travel or daily use. Clean the filter surface with a soft blower and lens cloth or microfibre tissue; for stubborn marks use a small amount of lens cleaning solution. Remove the filter only when necessary for specialized optical effects or when stacking other filters that require removal.

Usage recommendations

To maintain optimal performance, keep the multi-coated surfaces clean and store the filter in a protective case when not in use. When using on very wide-angle lenses, check for vignetting at initial setup; the ultra-slim frame is intended to reduce, but may not eliminate, vignetting in extreme wide-angle configurations.
