The Bower 82mm Filter Kit includes a 82mm UV Filter, a 82mm Circular Polarizer Filter, and a 82mm FLD Fluorescent Filter for Daylight Film. Each filter in this kit fits a lens with 82mm 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 82mm 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 82mm 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.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

To prevent internal ghosting and reflections, each glass surface on this circular polarizer includes one layer of anti-reflection coating.

The 82mm FLD Fluorescent Filter for Daylight Film is a color correction filter that is designed to reduce green casts when shooting with daylight film under fluorescent lighting. It is constructed from optical glass for clarity and an aluminum-alloy filter ring is featured for durability while remaining lightweight.

82mm UV Filter

Absorbs UV light and reduces bluish cast of daylight
Does not require adjustments to exposure while in use
Creates no additional coloration or contrast
General protection filter reduces dust, moisture, and scratches from reaching lens elements

82mm 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
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light
Clears up haze in distant landscapes and provides more saturated, vivid colors
Strongest effect when used at a 90° angle from the sun
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features
Single coated to prevent internal ghosting and reflections
2.5x filter factor reduces exposure by 1.3 stops

82mm FLD Fluorescent Filter for Daylight Film

Reduces green casts when photographing with daylight film under fluorescent lighting
2x filter factor reduces exposure by 1 stop
