The Ring Cross Filter POL comprises two polarizing filters and is used with the T10 Ring Flash 1. The outer, annular filter covers the flash tube. The inner, circular filter covers the camera lens and is orientated at right angles to the outer filter. These crossed polarizers are intended to reduce reflections of the annular flash tube in shiny subjects, including human eyes. The two polarizing filters cannot be rotated with respect to each other. Both filters are circular (not linear) polarizers, to allow the dual-mirror beamsplitter in the OM-4 metering system to function correctly.
The Filter screws into the font of the T10 Ring Flash, but it cannot be screwed all the way in – part of the screw thread is always visible; do not try to force it.
The Filter cannot be used in combination with the Zuiko Auto-Macro 20mm f/2 or the Zuiko Auto-Macro 38mm f/2.8 lenses, because they protrude through the T10 Ring Flash 1.
