The 40.5mm Skylight 1-A Filter is a general use filter with a slight pink tint to help improve overall color accuracy and clarity. The light pink coloration helps to reduce the overall bluish cast from daylight and is especially effective when photographing landscapes and in open shade.

The Skylight 1-A filter is also useful as a general protective filter to leave on lenses at all times. This filter helps to reduce dust and moisture from reaching your lens element and provides additional protection in case of drops or situations where abrasions could occur.
