Primarily developed to provide protection to the camera lens, the UV filter has a number of benefits. Not only will it filter UV rays up to 390mm & remove haze, it will also create an overall clearer, sharper image with a higher quality more professional appearance. Also, by covering the lens it gives added protection against grime & scratches that can cause the quality of images to otherwise significantly deteriorate. The protection of your camera lens can also help to increase the resale price of your camera when the time comes for an upgrade, because your lens is still in mint condition.
