Sony SLT-A77VM - Manual (Page 21)

High-density battery
The InfoLITHIUM ® NP-FM500H battery that
comes with the a77 provides plenty of power
for extended worry-free shooting. Compact
and lightweight, it recharges quickly and
packs enough power for approximately up
to 530 shots*. Precise indication of remaining
power is displayed through a 5-level battery
icon and a number that precisely represents
the percentage of power remaining in 1%
increments. When the camera is fitted with
an optional VG-C77AM vertical grip housing
extra batteries, up to 1,000 shots can be
taken between recharges.
Anti-dust Technology/System
Advanced dust resistance helps keep
your photos blemish-free. If dust particles
enter the camera when the lens is
being changed, two levels of protection
safeguard the image sensor. First, a
special static-free coating on the low-
pass filter covering the sensor helps
prevent dust from adhering. Second, an
anti-dust mechanism vibrates the filter
at high speed every time the camera
is switched off to dislodge any dust
particles that settled on its surface.
150,000 shutter release durability
Extended photographic pleasure is
assured by a remarkably durable shutter
unit. This newly developed unit has been
proven to endure approximately up to
150,000 shutter releases, a figure that rivals
high-end professional cameras. While
rugged enough to withstand the demands
of 12 fps continuous shooting, this high-
precision shutter unit also supports
everything from bulb shooting to ultra-fast
1/8000 sec. shutter speeds.
