Highly efficient standard circular polarizing filter for all cameras with beam
splitters in the light paths of their TTL exposure meter and with autofocus lenses.
Circular polarization has the same pictorial effect as linear polarization, but
allows for proper exposure metering and/or autofocus distance settings.
BandW Polarizers increase color saturation and reduce reflections. The neutral
gray color and plane parallel polarizer material guarantee optimal image results.
High-quality optical glass ensures excellent pictorial quality. The filter factor
varies according to how the filter is positioned in relation to the sun. Filter
factor is between 2.3 and 2.8.
MRC (Multi-Resistant Coating) by BandW is not only an extraordinarily effective
multiple layer coating, it is also harder than glass, so that it protects filters
from scratches (for instance when cleaning the filters), and it is also water
and dirt repellent, thus facilitating filter maintenance.
