This filter fits a lens with 52mm front filter threads. This filter is constructed from optical glass within an aluminum-alloy frame, which protect the front element of a lens from scratches, bumps, or impacts.
The Sunpak 52mm UV Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter.
This UV filter is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.
