Vivitar 77mm UV, Circular Polarizer, and Solid Neutral Density 0.9 Three-Piece Filter Kit

Vivitar 77mm UV, Circular Polarizer, and Solid Neutral Density 0.9 Three-Piece Filter Kit

EAN: 681066403044

This Vivitar Filter Kit includes three filters that each fits a lens with 77mm front filter threads and can provide a number of commonly applied enhancements to your imagery. Additionally, these filters are constructed using an aluminum-alloy frame, which can help protect the front element of a lens from scratches, bumps, or impacts.

Vivitar 77mm UV Haze Filter

The Vivitar 77mm 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.

Vivitar 77mm Circular Polarizer Filter

The Vivitar 77mm 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.

Vivitar 77mm Solid Neutral Density 0.9 Filter

The Vivitar 77mm Solid Neutral Density 0.9 Filter is an ND filter with an 8x filter factor that provides a 3-stop exposure reduction. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.
