With this UV filter from Polaroid you protect the front glass element of your lens against bumps and scratches. In addition, the filter absorbs UV radiation, so you prevent a blue haze on your photo. You can often see this haze back at sea or high in the mountains on your photos. The multi-coating prevents reflections and ensures that colors and contrasts remain neutral. Because the filter has no influence on the image quality of your photos, you can use it in any situation.
