1.11 Exterior and internal construction

１）Exterior and internal construction
The top, front, and rear covers are made of
magnesium alloy known for light weight and
high strength (Fig. 030). Also, the USB port,
video terminal, and other external interface
connectors concealed under the left cover use
special engineering plastic having excellent
electromagnetic shielding properties.
The camera body consists of a stainless
steel chassis and mirror box made of high-
strength engineering plastic. Also, the mirror
box, to which the mount and imaging element
are attached, is very securely attached to the
chassis to prevent the flange focal distance
from changing due to static pressure on the
attached lens. Since the grip and front cover
are one piece, the body rigidity is excellent. (Fig.
031)
The exterior surface finish is a high-quality,
black satin finish with a leathery touch. The
satin, leathery finish with finer graininess feels
smoother in the hands.
