Digitally Optimised (DG) Filters EX DG filters benefit from Sigma's multi-layer lens coating, developed to counteract the highly reflective characteristic of image sensors. With older style filters, light would reflect off the image sensor, bounce off the lens and filter elements and re-enter the image sensor, creating a ghost image. The multi-layer coating dramatically reduces this effect. In addition to this, an optimum, neutral colour balance is ensured, increasing the white balance accuracy of the digital camera. Wide Multi-Coated Circular PL It reduces the glare and reflections from glass and water and other non-metallic surfaces. It deepens blue skies, and saturates the colors. The Sigma circular PL filter is designed to give best performance with AF Cameras. You can monitor the changes at different angles through the viewfinder as you rotate this filter.

This Sigma Ex Circular Polarizer Filter is coated to repel water drops and resist smudging from fingerprints. It is also treated to exhibit antistatic properties to prevent microscopic dust from clinging to the front surface. This helps to ensure sharp images.

  • 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
  • Constructed from water, oil, and static resistant glass
