The Bower 58mm Filter Kit includes a 58mm UV Filter, a 58mm Circular Polarizer Filter, and a 58mm FLD Fluorescent Filter for Daylight Film. Each filter in this kit fits a lens with 58mm front filter threads and can provide one of three enhancements to your imagery. Additionally, these filters are constructed from optical glass within an aluminum-alloy frame, which protect the front element of a lens from scratches, bumps, or impacts. A filter case that can accommodate all three filters is included for storage and transport.

The Bower 58mm 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.

The Bower 58mm Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
