HR Digital Circular Pol 55mm GERMANY
The Rodenstock HR Digital Super MC
Circular Polarizing 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.
Rodenstock’s Digital Super MC filters feature a brass slimline filter mount with front filter threads. This allows
the attachment of other filters or lens hoods while still maintaing the
vignette-reduction capabilities of a slim filter. It is constructed from
16-layer, eight layers on each side, multicoated hardened optical glass.

Clears up haze in distant landscapes and provides more
saturated, vivid colors.
Strongest effect when used at a 90° 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
Hardened optical glass construction features a 16-layer
multi-coating to help prevent ghosting and reflection as well as increase light
Requires 1.5 fstop correction.
