Vertical grip for triple
battery advantage
The optional vertical grip (VG-C99AM)
features optimized contours and
essential controls that make vertical
shooting nearly as comfortable as
horizontal shooting. It can house
two batteries that combine with the
main battery to offer a three-battery
advantage that practically triples
shooting stamina whether shooting
still images or movies. The grip’s
batteries can also be changed while
continuing to shoot movies. Dust and
moisture resistance meet the same high
standards as the camera body.
Reliable anti-dust measures
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. The first
level of protection is a newly developed
coating on the surface of the optical
low-pass filter. Even in the most adverse
temperature and humidity conditions, this highly effective Anti-dust Coating
effectively suppresses the attachment
of both dry and moist dust particles and
simplifies their removal. The second level
of protection is an anti-dust mechanism
that vibrates the filter at high speed
every time the camera is switched off to
dislodge any dust particles that settled
on its surface.
