The 39mm UV + Circular Polarising (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 polarising filter, which can be easily screwed onto the lens. The UV filter protects the lens from dust, scratches, and other environmental influences while also reducing unwanted UV radiation that can cause a blue tint in images. The circular polarising filter, on the other hand, allows for minimising reflections from non-metallic surfaces and increasing colour saturation, which is particularly beneficial in landscape and nature photography. Both filters are designed not to compromise image quality and ensure a clear view of the subject. With a diameter of 39mm, this filter kit is ideal for a variety of lenses and provides photographers with the opportunity to achieve creative effects while also protecting their equipment.
