Canon UV-1 58mm Haze Filter

So) Canon 58Mm Uv Filter

The Canon UV-1 filter for 58mm lenses absorbs harmful ultraviolet rays without increase of exposure, thereby preventing haziness and foggy effects in distant landscapes. It also has a very subtle warming effect, which can be useful to counter the "cool" colors you sometimes get in bright sun or in shade. It can be left on the lens at all times for protection of the camera's lens.
