18ex28B IASE
INTRODUCTION
The HJ18ex28B IASE is a truly unique new Super
Telephoto portable high definition EFP lens.
This lens is intended for producers and broadcasters who cover
special events, concerts, documentaries, natural history, and the
many other challenging location productions that seek superb image
capture over very considerable distances using highly mobile HD
acquisition systems. Weighing in at only 5.5 lbs and an overall
length of 10.5 inches this remarkable lens offers the longest focal
length of any lens in its class. And requires no mechanical support
system to mount to the HD camera. Aerial shooting (using stabilized
gimbals), sports and entertainment coverage, and portable HD acquisition
in arduous terrain – are all superbly supported by this low-weight
compact lens.
ABOUT THIS LENS
The HJ18ex28B IASE is a high definition EFP lens
that brings entirely new shooting flexibilities to field production.
The HJ18ex28B can extend to 500mm focal length (and to 1000mm with
the extender). It has a very impressive optical speed of F2.8 up
to a focal length of 286mm. The lens represents the very best in
contemporary optical and mechanical design.
The lens combines creative flexibility and mobility in a portable
HDTV camera system with the demanding performance requirements for
high-end HDTV image acquisition at long focal lengths. The design
optimization strategies include a very respectable sensitivity,
maximization of image contrast, and preservation of the highest
MTF over the long focal ranges.
High contrast is ensured by superb control of black reproduction
– with optical and mechanical design innovations that substantially
reduced flare, veiling glare, and any internal reflections. Similar
attention to minimization of ghost images and other highlight-related
chromatic distortions caused by strong light sources on-axis and
off-axis further extend the operational contrast range of the lens.
