The EOS-1v was developed
using the strongest available
body materials for both
functional attractiveness and
high-level rigidity. The
magnesium alloy used for the
EOS-1v is lightweight, yet possesses exceptional strength. Although
hard to machine, Canon uses an advanced injection molding
technology called “thixo-molding” to mold the delicate curved
surfaces of the EOS-1v body. This lightweight body is the perfect
blend of rigidity, durability and total precision.
Rigid, reliable diecast aluminum is used for the lens mount on the
front panel, and for the front mirror unit—areas critical to the
precision of an SLR camera. The EOS-1v’s reliability is heightened
by its diecast aluminum body and a simplified structure that has
no lens driving pin and processes all data electronically.
Magnesium alloy is used for the distinctive top and front covers
of the EOS-1v, and for the outside covers of the PB-E2
Power Booster. The structure encloses the inner
workings with rigid covers, thus increasing internal
strength and protecting system precision as a whole.
The EOS-1v was built to deliver top performance
regardless of the shooting environment. All parts are
precisely machined. The aperture and hybrid framework
structure which serve as the base for various parts and
fittings are diecast aluminum, with glass-fiber reinforced
polycarbonate resin, which is equal in strength to metal.
The main outside covers are made of magnesium alloy.
The lightweight body benefits from remarkably
improved rigidity, precision, and durability, realized by
the optimum use of carefully chosen high-tech materials.
The glass-fiber reinforced
polycarbonate resin body has
die-cast aluminum inserts
around the aperture area while exterior components
are made of lightweight, rigid engineering plastic.
Inner surfaces are coated in copper-plating to provide
electromagnetic shielding. The body package as a
unit is highly shock-resistant and well protected against
noise as befits a camera that houses advanced electron-
ics. In addition, both the front (including the grip) and
rear covers of the PB-E2 Power Drive Booster are made
of magnesium alloy. This tough, lightweight material also acts as an
electronmagnetic shield.
The greatest threats to a
camera that is loaded with
advanced electronics are
exposure to environmental hazards such as rain and/or
dust. The EOS-3 was built to exhibit superior
protection against these threats and thereby provide
the highest level of durability under even the severest
shooting conditions.
All buttons and dials use rubber gaskets to block out
drops of water. And for greater reliability, all the
important electrical contacts are bipolar and gold-
plated. To protect the heavily-used Main Dial, it too was designed
to repel water away from it.

EOS-1v CONSTRUCTION
Combines strength and
elegance to deliver top
performance regardless of
the shooting environment
Professional cameras must be impervious
to sharp changes in temperature; they
must also be resistant to water, sand and
dust. They must work
smoothly under a
wide range of conditions.
The EOS-1v has
been developed and manufactured to reflect feedback from
professional photographers who work in severe environments, as
well as Canon’s own expertise in this area.
Following a reassessment of the severity of conditions that may
apply in some shooting situations, Canon has succeeded in raising
the level of water and dust resistance. The 72 major body seams
and moving parts, such as the shutter button, selector buttons and
Main/Quick Control Dials, are carefully sealed with silicone
rubber, and the edges of the back cover are thoroughly finished.
Furthermore, the battery chamber located inside the new grip
GR-E2 is protected by packing, while the insides of function
buttons, found on the upper left of the body, are protected from
dust and water by a silicone rubber boot.
The satisfyingly solid feel and sound of the
back cover being closed will tell you that
the EOS-1v stands up to the elements like
no other camera.
In addition to shielding the moving parts
and major seams in EOS-1v body against
water and dust, complete measures were
taken to secure the lens mount perimeter.
The lens mount is protected by a water-
resistant rubber O-ring. When the EOS-1v
is used together with an IS super-telephoto
lens, unrivaled performance is assured in a
wide range of shooting conditions.
