This Vivitar Filter Kit includes three filters that each fits a lens with 67mm 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 67mm UV Haze Filter
Vivitar 67mm Circular Polarizer Filter
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.
