Advanced UV Filtration for High-Clarity Imaging

Calumet engineered the UV SMC TG Ultra Slim Filter series to block ultraviolet light before it reaches the camera sensor. These filters perform exceptionally well in high-altitude or coastal environments with high UV intensity. The filter enhances overall contrast and sharpness by suppressing UV wavelengths that cause haze, revealing clearer and more defined distant elements.

28-Layer Multicoating for Superior Optical Performance

Each filter in the series uses a sophisticated 28-layer multicoating system—14 coatings on each side of the glass. These include anti-reflective coatings to minimise internal flare, hydrophobic and oleophobic layers to repel water and fingerprints, and a scratch-resistant coating to prevent surface damage. The multilayer system maintains high transmission, reduces ghosting, and simplifies maintenance in harsh shooting environments. Photographers can expect consistent, high-resolution results even in harsh, high-contrast lighting.

Japanese AGC Optical Glass with 99.6% Light Transmission

Calumet chose premium Japanese AGC glass for its exceptional optical clarity and strength. The glass transmits 99.6% of incoming light, allowing the sensor to receive accurate exposure without introducing colour cast or distortion. Professional photographers rely on this level of performance to preserve detail, colour accuracy, and tonal balance in landscape, architectural, and product photography.

Durable, Ultra-Slim Aerospace Aluminium Frame

Calumet designed a frame just 3.3mm thick using aerospace-grade aluminium to prevent vignetting on wide-angle lenses. The material offers a high strength-to-weight ratio, while the integrated tabs provide a firm grip for quick filter changes—even in gloves or wet conditions. The double-threaded mount allows photographers to stack additional filters or accessories like lens hoods or ND filters without compromising fit or alignment.

Hard-Coated Glass for Field Durability

Calumet strengthened the glass to 6H hardness through chemical tempering, which helps resist scratches, impacts, and wear. Photographers can confidently handle the filter in rugged outdoor locations or high-use studio environments, knowing it will retain optical quality through repeated use and exposure to dust, salt, or moisture.

FAQs:

What is the difference between Calumet's UV MC and UV SMC TG series?

The UV MC series offers reliable lens protection and image clarity with 24 multi-coated layers, which is ideal for everyday use. The UV SMC TG series is a higher-end option built for professional demands, featuring 28 advanced coatings, including hydrophobic, oleophobic, and anti-reflective layers, plus 6H hardened Japanese AGC glass for superior durability and optical precision.

Can I stack the Calumet UV SMC TG filters?

Yes, the Calumet UV SMC TG filters feature a double-threaded aluminium frame, allowing you to stack them with other filters or screw-in accessories such as ND filters, polarisers, or lens hoods. The ultra-slim 3.3mm profile helps prevent vignetting, even when stacking on wide-angle lenses.

What is the best way to clean Calumet's UV SMC TG filters without damaging them?

Use a blower to remove loose particles, followed by a microfibre cloth and lens cleaning fluid suitable for coated optics. The hydrophobic and oleophobic coatings make cleaning easier and reduce the chance of smearing. Avoid abrasive cloths or tissues, which can compromise the coating's performance over time.
