Fast signal processing makes the PowerShot G2 feel much more
like a film-based camera than any previous digital camera could.
The dedicated digital signal processing IC (integrated chip)
eliminates the old compromise between long processing times
and poor image quality. Combined with the camera’s buffer
memory, the high-speed IC allows shots at 1.6-second intervals
in single capture mode and up to 5 high-quality images at 2.5
images per second in high-speed continuous mode.
The PowerShot G2 will record images in any of three levels of
JPEG compression – normal, fine, superfine – or as CCD RAW
files. This allows you to decide between having more storage
space available for more images, or a superior image quality for
fewer pictures. RAW image processing, which compresses a
signal without any loss of resolution, has been improved to
require less memory than earlier systems used.
There are two different autofocus modes, both of which can be
shut down so you can focus manually. In
Single mode
, battery
power is conserved by shutting off the LCD monitor while the
photographer uses the optical viewfinder.
Continuous mode
maintains a focused image on the LCD at all times.
In either mode, the user can select
single-point AF
for rapidly
shooting a subject in the center of the frame, or 3-point selectable
ranging AF.
3-point AF
allows selection of any of three points as
the distance ranging point so that an off-center subject can be
selected without having to first be centered and focused.
The PowerShot G2 also supports
Macro
photography at distances
down to 2.4 inches at the wide end of the lens and to 7.9 inches
at the telephoto end. The vari-angle LCD monitor makes framing
macrophotographic
shots easier.
Just as Canon gives you a choice of autofocus modes in the
PowerShot G2, it now adds evaluation metering to your choices
of automatic exposure systems.
Spot metering
and
Center-
weighted averaging metering
measure the light with a strong
emphasis on a central subject and a lesser emphasis on back-
ground.
Evaluation metering
divides the screen into blocks,
evaluates lighting
factors and assigns
the best exposure for
each individual block.
