Pre PMA - Rodenstock HR Filters
Direct
Source Marketing, (D.S.M.), U.S. Distributor of High-end Rolleiflex and
Horseman Cameras, to Unveil Rodenstock HR Filters at PMA That Exceed
New Advanced Digital Standards
SW-DII Pro Super Wide Angle Camera and LD Camera Will Also Be Shown
Las Vegas, Nevada, March 6, 2007 - Direct Source Marketing, the U.S.
distributor for medium and large format Horseman and Rolleiflex
professional cameras, will exhibit at PMA beginning Thursday a series
of Rodenstock HR advanced filters designed to bring out the best in
optical performance for the new, advanced digital standards, plus a
super wide angle camera and a high-end camera for mounting high-end
digital backs.
D.S.M. was created as a result of the joint venture between Komamura
Corporation, a long time distributor of Rollei and Horseman products in
Japan, and Franke & Heidecke, the Germany-based manufacturer of
Rollei professional products and Horseman components.
In addition to the filters, Komamura/Franke & Heidecke will exhibit
Horseman's SW-DII Pro, one of the widest angle cameras on the market,
and the Horseman LD Pro, a camera that lets the photographer tilt and
shift for sharpness control.
The filters, which carry the Rodenstock HR (high resolution) label, are
manufactured to meet Rodenstock's stringent standards for optical
performance. Rodenstock is a long time leader in the design and
manufacturing of professional optics.
One of the most unique features of the new Rodenstock HR Digital
Filters is the use of special optical glass. Rodenstock's use of high
transmission glass provides a cleaner path of visible light and reduces
ultra violet rays below 400 nm, which is important because the new
digital standards require the ability of light to pass straight through
to the imager.
The new filters feature extremely hard, digital multi-coating with five
coats, the last which is water shedding and causes water to literally
run off the filter like water on a waxed car. The filters also have
edge coating, which reduces internal reflection and won't delaminate.
The use of thinner optical glass provides less aberrations and better
light transmission, as well as permitting the use of thinner filter
mounts.
Quality design and construction is reflected in unique brass rings,
which help ensure optical alignment of the filter to the lens and
safety features, such as a sufficient amount of threads to ensure lens
cap attachment, and a thin filter ring for full frame shooting without
vignetting when using wide angle lenses.
