Mechanical Protection of the Imaging System
Experiences gleaned from the EOS C300 camcorder exposed the hard reality that accidental
physical shocks – as incurred when lens-camera systems fall from tripods or are subject to
unexpected blows – can incur expensive damage to either the lens or camera imaging system
(or both)
.
Innovative mechanical design strategies have been introduced into the EOS C300
Mark II to ameliorate the possibilities of such damage.
The die-cast superstructure is made up
of the three mechanical subsystems shown in Figure 5 – where the ND filter subassembly and
CMOS image sensing system is mounted within the Imaging Unit.
This is a floating structure
that is secured to the Front Frame Unit via a Base Plate.
The latter is made of a special metal
material that is designed to absorb the shock of any traumatic external force – Figure 6.
