Urth 39mm Plus+ Magnetic Duet Kit - UV/CPL

The UV filter primarily protects your lens and reduces ultraviolet light haze for clearer shots, especially at higher altitudes. The CPL (Circular Polarizer) filter reduces glare and reflections from surfaces like water and glass, and enhances color saturation, particularly the blue of the sky.

Yes, this kit includes a magnetic adapter ring. You screw this ring onto your 39mm lens thread, and then the filters magnetically attach to this ring. If your lens thread is not 39mm, you will need to purchase a separate Urth magnetic adapter ring for your specific lens thread size.

Yes, the magnetic system allows you to stack filters easily. You can attach the UV filter and then magnetically attach the CPL filter on top of it, or vice-versa.

The 'Plus+' designation typically refers to Urth's enhanced coatings or design features, such as improved UV filtering capabilities that also address polarized light for greater clarity and color intensity.

With every Urth filter purchase, including this Duet Kit, Urth partners with environmental organizations to plant trees in areas affected by deforestation. This helps support local communities and restore ecosystems.

The kit includes metal protective caps designed to safeguard the filters when they are not in use.

Yes, these are designed as standard camera filters. The CPL filter may slightly affect exposure metering due to light reduction, but autofocus and auto-exposure systems are generally compatible. The magnetic attachment ensures precise alignment, which is crucial for these systems.

Ensure the magnetic adapter ring is properly screwed onto the lens and that there is no debris obstructing the magnetic surfaces of both the ring and the filter.

This can occur when stacking multiple filters, especially on wider lenses. Try removing one filter, or ensure you are not using the extreme wide end of your zoom lens. Check if the included adapter ring adds significant thickness.

Ensure the filter glass is clean. If the issue persists, verify the filter is correctly seated and that no other filters or accessories are interfering with its alignment.

Rotate the CPL filter relative to the lens. The effect of a CPL filter is dependent on the angle of light and the reflective surface. You may need to adjust your shooting angle or lens position.
