The Heliopan 40.5mm UV SH-PMC Filter is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight (which can cause outdoor photos to appear hazy and indistinct). No additional coloration or contrast is provided, allowing you to pair this filter with others. The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.
