UV Filter Calumet SMC TG 49 mm Ultra Slim 28 Layers

Calumet SMC TG UV Filter 49 mm Ultra Slim with 28 coating layers is a low-profile protective filter that reduces ultraviolet haze and preserves image clarity. The ultra-slim frame minimizes the risk of vignetting on wide-angle and standard lenses while the multi-layer coatings enhance light transmission and reduce reflections. This filter is designed to stay mounted during everyday shooting, providing front-element protection without altering colour balance or contrast.

Advantages

The ultra-slim metal frame reduces vignetting on wide-angle lenses and provides a secure, low-profile fit. Twenty-eight anti-reflective and protective coating layers improve light transmission, lower flare and ghosting, and support accurate colour reproduction. The filter functions as both a UV-cut and mechanical protector, shielding the lens surface from dust, moisture and minor impacts while remaining optically neutral for most shooting conditions.

Suitable for

• Landscape and outdoor photography with wide-angle lenses
• Everyday shooting where front-element protection is needed
• Standard prime and zoom lenses requiring low-profile accessories
• Situations that demand reduced ultraviolet haze and improved image clarity

Key specifications

• Filter thread size: 49 mm
• Frame style: ultra-slim, low-profile metal mount
• Coating: 28-layer multi-coating for anti-reflection and protection
• Primary function: ultraviolet light reduction and front-element protection
• Optical effect: minimal colour cast, neutral transmission characteristics

How to use

Screw the filter onto the front thread of a compatible 49 mm lens until it seats securely by hand, avoiding overtightening. Use the filter continuously during outdoor daylight shooting to reduce UV haze and protect the lens surface. Clean the filter with a soft microfiber cloth and lens-cleaning solution as needed; handle by the metal frame to avoid fingerprints on the glass. When stacking filters or using wide-angle lenses, confirm that the ultra-slim mount prevents vignetting in your specific setup.

Usage recommendations

Use the Calumet 49 mm ultra-slim UV filter on wide-angle and standard lenses where a low-profile mount is required. Remove grit before mounting, store in a protective case when not in use, and avoid applying excessive force when attaching or removing the filter to preserve the frame and coating integrity.
