What the Duet Filter Kit includes
The Urth 62mm Duet Filter Kit pairs a UV filter with a circular polarising filter. Both use Japanese AGC optical glass and ultra-slim magnalium rims. The kit suits photographers who want lens protection and reflection control in one purchase.
How the bundled filters change results
The UV filter cuts 99.6% of ultraviolet light to reduce haze and a blue colour cast while protecting the front element from scratches, dirt and water. Its 8-layer nano-coating aids sharpness and cleaning. The CPL filter cuts reflections and boosts colour saturation. Both rims are double-threaded for stacking or screw-mount caps.
Installing the filters and common issues
Thread each filter onto a 62mm lens front; the ultra-slim rim avoids vignetting on wide angles. Double threads let you stack the CPL over the UV or add a cap. The main issue is forgetting to rotate the CPL for the desired polarisation effect, which varies with shooting angle.

Questions about this item
Will the nano-coating on the UV filter eventually wear off and need replacement?
The 8-layer nano-coating is bonded to the Japanese AGC glass and is designed to withstand repeated cleaning; it does not have a specified service life.
What is the first optical limit reached when stacking both filters on a wide-angle lens?
The ultra-slim magnalium rims are engineered to avoid vignetting, so stacking the UV and CPL filters together should not introduce corner darkening on 62mm threads.
How much heat does the CPL filter absorb during all-day outdoor shooting?
The CPL filter transmits visible light while blocking polarised reflections; it does not convert light into measurable heat, so the filter rim remains at ambient temperature.
