Panasonic Lumix G Vario 100-300mm f/4-5.6 II POWER O.I.S. Lens with Circular Polarizer Filter Kit

A long-reaching telephoto zoom for Micro Four Thirds cameras, the Lumix G Vario 100-300mm f/4-5.6 II POWER O.I.S. Lens from Panasonic spans an equivalent 200-600mm range, making it well-suited to wildlife, nature, and sports shooting. The optical design incorporates one extra-low dispersion element to reduce color fringing throughout the zoom range, as well as to provide improved clarity and color accuracy. Benefitting the optics, the lens also houses a quick, quiet, and precise linear autofocus motor as well as a POWER Optical Image Stabilizer, which supports the Dual I.S. function in select Lumix cameras. Additionally, the lens also sports a splash and dustproof construction for use in trying environmental conditions.

The Hoya 67mm alpha 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.

This filter is non-coated and has approximately 96% average light transmission. It is constructed from optical glass and precision milled aluminum frames.
