Outstanding reliability
Robust enough to meet any challenge
A strong, lightweight body
For rugged and reliable performance under adverse
conditions, the top and front covers of the
’s body
are constructed of a strong, lightweight magnesium alloy.
Within the camera, a high tensile-strength aluminum alloy
chassis and high-rigidity engineering-grade plastics fur-
ther contribute to high structural integrity and low weight.
Aluminum alloy chassis
Protected against dust and moisture
No matter how strong internal and external body
components are, cameras will be subject to damage
if they are not protected against dust and moisture*.
On the
, buttons, dials, and switches are protect-
ed by gaskets and sealants for worry-free shooting
outdoors.
High-endurance shutter unit
To ensure long-term reliability under heavy use, the

sion, high-speed shutter unit that offers outstanding
durability. Capable of withstanding the performance
demands of 1/8000 sec. shutter speeds and 5 fps
continuous shooting, the shutter unit has a service
life of approximately 100,000 operating cycles, and is
optimized to enable high-precision Super SteadyShot
