Robust magnesium alloy body
The rigidly constructed a99 is supremely lightweight. Its rugged magnesium-alloy
top and rear panels interlock with front and side panels constructed of highly rigid
engineering plastic to offer protective external shielding. Inside, a rigid magnesium
chassis reinforced by stainless steel and other structural components contributes to
a supremely rigid and lightweight camera able to withstand passionate usage in
challenging conditions.
The world’s lightest camera with full-frame sensor*
Supremely lightweight construction contributes to agile handling in the field that,
combined with full-frame performance, gives the a99 unrivaled appeal. Record-
breaking lightness was achieved through the use of lightweight materials like
magnesium alloy and engineering plastic, as well as the elimination of unnecessary
mechanisms such as heavy pentaprisms and active mirrors, thanks to Translucent
Mirror Technology.

200,000 shutter
release cycles
The new extremely durable
shutter unit has been proven to
endure approximately 200,000
shutter releases, a figure that
rivals high-end professional
cameras. While rugged enough
to withstand the demands of
6fps
(
10fps in tele-zoom mode
)
continuous shooting, it offers
exceptional precision at shutter
speeds up to 1/8000 sec. made
all the more accurate by the
continuous support of auto
diagnosis and correction. This
proven combination of supreme
accuracy and durability lets
you shoot year upon year
without worrying about wearing
out the shutter unit.
Dust and moisture protection
Comprehensive dust and moisture
resistance contributes to high reliability.
Sony tightly interlocked the panels
and components, added sealing
around most buttons and dials, and
placed gaskets along the edges of
the viewfinder and LCDs
(
top and
rear
)
to help prevent water and dust
from entering the body during tough
usage. Similar protection was applied
to openings such as the media
compartment, which is protected by an
interlocking structure. Jack covers are
fitted with rubber-based covers for better
sealing and are organized by function
to minimize opening and closing. The
front section of the accessory shoe is
also constructed of highly dust/water
resistant parts.
