Urth 49mm Duet Filter Kit UV CPL camera filter

Essential Lens Protection and Enhancement Kit

The Urth 49mm Duet Filter Kit pairs a UV filter with a circular polarising filter, giving photographers a compact two-filter set that protects front elements while controlling reflections and atmospheric haze. Both filters use Japanese AGC optical glass mounted in ultra-slim magnalium rims designed to avoid vignetting on wide-angle lenses. Double-threaded frames allow stacking or the use of screw-mount lens caps without removing the filter. This kit suits shooters who want everyday protection plus creative polarisation control in a single purchase.

Ideal for Everyday Shooters, Not Specialised Needs

Photographers who regularly work outdoors, near water or through glass will benefit from the CPL filter’s ability to cut 99.9% of polarised light and deepen colour saturation. The UV filter removes 99.6% of ultraviolet light, reducing blue cast in misty conditions while shielding the lens from scratches, dirt and moisture. Buyers who need variable ND density, infrared transmission or filter sizes other than 49mm should look at alternative solutions, as this kit addresses only standard thread protection and linear polarisation.

Double-Threaded Design Expands Creative Options

The double-threaded construction on both filters lets you stack additional filters directly on the front thread, enabling combinations such as UV plus CPL plus ND without vignetting thanks to the ultra-slim rim profile. The same front thread accepts standard screw-mount lens caps, so you can cap the lens while the filter remains fitted, speeding up workflow in changing conditions. Japanese AGC glass with multi-layer nano-coating maintains optical clarity across the stack, preserving sharpness and contrast for professional results.
