Product description

• Panasonic Lumix G 20mm f/1.7 II ASPH. Lens (Black) Characterized by its slender profile, the black Lumix G 20mm f/1.7 II ASPH. from Panasonic is a compact, slightly wide 40mm equivalent prime for Micro Four Thirds mirrorless cameras. Its bright f/1.7 maximum aperture offers notable control focus for working with shallow depth of field techniques and also benefits working in difficult lighting conditions. The optical design incorporates a pair of aspherical elements to suppress spherical aberrations and distortion for high sharpness and accurate rendering, and individual elements have also been multi-coated to control surface reflections and flare for improved contrast in strong lighting conditions.
  • Slightly wider-than-normal prime is designed for Micro Four Thirds mirrorless cameras and offers a 40mm equivalent focal length.
  • Bright f/1.7 maximum aperture benefits working in low-light conditions and also affords greater control over depth of field for working with selective focus techniques.
  • Two aspherical elements are used to reduce spherical aberrations and distortion in order to realize greater sharpness and resolution.
  • Individual elements have been multi-coated to effectively reduce lens flare and ghosting for improved contrast when working in strong lighting conditions.
  • Autofocus motor supports camera's contrast detection for precise focusing performance. AF can also be manually overridden for more fine-tuned control.
  • Pancake form factor measures just 1"-thick, making it ideal for everyday and travel use.
  • Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.

• Vu Filters 46mm Sion Slim Circular Polarizer Filter The 46mm Sion Slim Circular Polarizer Filter from Vu Filters 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.
  
  Sion Slim circular polarizer filters are multi-coated, have approximately a greater than 85% average light transmission, and are constructed from Schott glass with a black rim. Set within aluminum-alloy filter rings that are durable while remaining lightweight, the glass elements provide increased clarity as well as color fidelity, while their black rims further ensure that reflections do not occur along the filter's edge. The Flat Wave Overcoat associated with this Sion Slim circular polarizer filter provides an additional layer over the multi-coatings, resulting in an improved beading effect to repel water for greater cleaning efficiency.
  
  This 46mm Sion Slim Circular Polarizer Filter's ring assembly is 3.4mm thick, to help maximize vignetting prevention. It can be rotated in order to adjust the intensity of the polarization effect, and features side knurling to provide a more textured grip for mounting or removing the filter from a lens.
  • 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.
  • Multi-coated to prevent internal ghosting and reflections as well as to ensure color fidelity.
  • Flat Wave Overcoat repels water with an improved beading effect for more efficient cleaning.
  • Greater than 85% average light transmission.
  • 2 to 2.8x filter factor reduces exposure by 1 to 1.5 stops.
  • Constructed from Schott glass for optical clarity.
  • Black rimmed glass further ensures that reflections do not occur along the filter's edge.
  • Slim, 3.4mm-thick, aluminum-alloy filter ring assembly helps to maximize vignetting prevention, while remaining lightweight.
  • Filter ring assembly can be rotated to adjust the intensity of the polarization effect.
  • Side knurling to provide a more textured grip when mounting or removing it from a lens.
  • 46mm front filter threads allow for use with other filters.
  • Plastic filter case for storage and transport.
