Heliopan 49 mm Circular Polarizing Glass filter - Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.

Note: Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems)


FEATURES
  • Fully calibrated to indicate the axis of polarization and the convenient markings make the filters very easy to use on non reflex and non ground glass focusing cameras
  • With the calibrations all that is necessary is to hold the filter up to the eye and rotate it until the desired effect is seen; Note the position of any number on the rim, mount the filter on the lens and rotate the mount until the selected number is in the same position as when the filter was held to the eye
  • The effect can be seen through the viewfinder and changed by rotating the filter
  • The filter factor varies according to how the filter is rotated and its orientation to the sun
  • Made of black anodized brass stock and have so little rim in front of the lens (5.4 mm) that they will not vignette with lenses as short as 21 mm
  • Heliopan filters are "dyed in the mass" and ground, polished and coated to the highest standards of the German optical industry
  • All Heliopan screw-in type and series size filters are mounted in precision black anodized brass rings to eliminate binding or cross threading and to ensure optimal alignment
