The XC-ST50 uses the latest 1/2" Interline Transfer
(IT) CCD with HAD technology which is more sensitive
than the technology used in the popular XC-75 and
XC-73 camera family. This new HAD technology has a
microlens over each pixel to improve the light collection
efficiency. This is reflected in the minimum sensitivity
specification of 0.3 lx. That means the camera should
be able to detect more faint signals or need less
gain with less noise when detecting faint signals.
The XC-ST50 have all the camera control switches accessible
from the outside of the camera. There is no need for
the user to open the camera to modify the operating
mode of the camera or to determine or confirm switches
settings. A user will no longer need to "customize"
the internal camera switches.
The XC-ST50 has an improved trigger/shutter that significantly
improves and simplifies the trigger operation from
previous models. The various versions of Reset-Restart
and Donpisha are now replaced with a simplified trigger/shutter
that provides much greater functionality and flexibility.
Now, the shutter speed of the external trigger shutter
can be specified by the width of an external trigger
pulse or switch setting in the rear panel. With this
function, the XC-ST50 can take a clear image of a
fast moving object.
The XC-ST50 is a small, lightweight one-piece camera.
The camera body's measurements are 29 x 44 mm (same
as the XC-75/73); however, the camera depth measures
only 57.5 mm long, approximately 19% shorter than
the popular XC-75/73 at 71mm. The camera weighs only
110 grams, approximately 20% lighter than the XC-75/73
at 140 grams. The compact, lightweight camera body
allows the camera to be used in very tight places
and for some remote camera-head applications.
The XC-ST50 has improved vibration resistance. Vibration
resistance has been improved to 10G as compared to
the XC-75/73 at 7G. The improvement in vibration resistance
is achieved by improved board-to-board connections.
The compact size and improved vibration resistance
makes the XC-ST50 even more viable as a remote head
camera replacement. The XC-ST50 can resist up to a
70G shock.
