Sony E 20mm f/2.8 Lens with Circular Polarizer Filter Kit

Complementing the lens itself, the Sony E 20mm f/2.8 Lens with Circular Polarizer Filter Kit from B&H bundles the slim wide-angle prime with a 49mm circular polarizer filter.

• Sony E 20mm f/2.8 Lens

  Begin your wide-angle journey with the E 20mm f/2.8 Lens from Sony , a super compact "pancake" lens designed for APS-C-format E-mount cameras where it provides a 30mm equivalent focal length. It offers shooters a fast f/2.8 aperture for use in low light and for creating images with a shallow depth of field. Benefitting image quality are three aspherical elements to minimize the appearance of aberrations while a rear focusing design improves autofocus speed and helps reach a minimum focus distance of 7.9". Additionally, the lens is equipped with a seven-blade circular diaphragm for smooth, rounded bokeh.

  With its pancake design, the lens only extends 0.8" from the mount, resulting in a compact and lightweight camera system.

  Optimized for APS-C-format cameras, this compact 20mm lens offers a wide-angle 30mm equivalent focal length.

  The fast f/2.8 maximum aperture permits operation in less-than-ideal lighting situations and allows photographers to capture images with shallow depth of field.

  Three aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.

  The lens uses a rear focusing design that contributes to faster autofocus performance as well as a minimum focus distance of 7.9".

  Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.

• Hoya 49mm alpha Circular Polarizer Filter

  The Hoya 49mm 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.

  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.

  Non-coated.

  Approximately 96% average light transmission.

  3 to 4x filter factor reduces exposure by 1.6 to 2 stops.

  Constructed from optical glass and precision milled aluminum frames.

  Plastic filter case for storage and transport.
