The Starblitz UV filter ensures your outdoor photos will have natural colours. By suppressing the invisible ultraviolet component of sunlight, it reduces the bluish tint occasionally caused by UV glare to give your photos a natural colour without the need for further software editing. This phenomenon occurs more frequently at higher altitudes and near reflective areas, making this product ideal for the sea and the mountains. The Starblitz 40.5mm UV filter also somewhat protects your lens against water, dust and scratches. It can be used in conjunction with a sun hood to protect the lens from sudden changes in lighting.
