The 40.5mm UV + Circular Polarizing (CPL) Lens Filter Kit from Urth is a versatile accessory for photography enthusiasts looking to enhance their image quality. This kit includes both a UV filter and a circular polarizing filter, both specifically designed to optimize lens performance. The UV filter protects the lens from dust, scratches, and unwanted UV rays, while the circular polarizing filter helps reduce reflections and increase color saturation. Both filters are designed as screw-on filters, allowing for easy attachment and detachment. With a diameter of 40.5mm, this filter kit is ideal for a variety of lenses and provides photographers with the opportunity to achieve creative effects and improve the clarity of their shots. Using these filters can be particularly beneficial in bright environments or when shooting water and glass, as they enhance visibility and detail fidelity.
