| Canon has finally announced the long-awaited
new G series compact to replace the G6 (launched August
2004). The $550 PowerShot G7 features a new Digic III processor,
10 megapixel (1/1.8-inch) CCD and a 6x (35-200mm equiv.)
image stabilized zoom lens. The G7 also sports a hot shoe,
face detection software and ISO settings up to 1600. Disappointingly
what it doesn't have is a raw mode, which appears to have
been completely dropped by Canon for its compact models
- presumably to protect the sales of entry-level digital
SLRs.
Press Release:
PowerShot G7: Canon's most complete compact yet

Amstelveen, The Netherlands,
14 September, 2006: Canon
today launches the eagerly awaited PowerShot G7. Following
the celebrated PowerShot G6, the classically styled PowerShot
G7 boasts an advanced feature set that includes 10.0 Megapixel
resolution, a 6x optically image stabilised zoom lens and
Canon's new DIGIC III image processor.
DIGIC III delivers rapid performance with
improved image quality and incorporates two new Canon technologies
- Face Detection AF/AE and advanced Noise Reduction, which
extend the camera's low-noise performance to ISO 1600. The
high-resolution 2.5” LCD screen has a wide viewing angle
and anti-glare coating for easier image framing and playback.
Furthering the potential for creative photography, the PowerShot
G7 is equipped with hot shoe support for Canon Speedlite
flash units and is compatible with a range of optional converter
lenses.
PowerShot G7 will be available from early October.
The PowerShot G7 features:
- 10.0 Megapixels
- 6x optical zoom lens with optical Image Stabilizer
and SR coating
- DIGIC III and iSAPS with Advanced Noise Reduction
and Face Detection AF/AE
- 2.5” high-resolution LCD with wide viewing angle
and anti-glare coating
- ISO 1600 for flash-free, low light shooting
- Ergonomic design with dedicated ISO and Multi
Control dials for fast, easy operation
- 25 shooting modes including full manual control
and 2 custom settings
- Extra telephoto reach with Digital Tele-Converter
and Safety Zoom
- Hot shoe support for Canon Speedlite flashes
and optional lens accessories
“The PowerShot G7 brings a new level of performance and
usability to the G series,” said Mogens Jensen, Head of
Canon Consumer Imaging Europe. “By introducing our DIGIC
III image processor and new technologies such as Face Detection
AF/AE, Canon continues to raise the benchmark for digital
compact cameras."
Image Quality and Optics
The PowerShot G7 delivers the image quality and optical
performance demanded by advanced photographers. A 10.0 Megapixel
sensor captures enough fine detail to ensure large photo
quality prints with added cropping flexibility. The fast
f/2.8 (W) – f/4.8 (T) 6x optical zoom lens (35-210mm focal
length, 35mm equivalent) incorporates optical Image Stabilizer
technology to counteract the effects of camera shake, allowing
the camera to be used at slower shutter speeds in low light
conditions. The lens configuration consists of 9 elements
in 7 groups and includes a double-sided aspherical lens
element to counteract common lens distortions. The addition
of Canon’s SR lens coating – a first for Canon's digital
compact camera range – significantly reduces the problem
of ghosting and virtually eliminates chromatic aberration.
DIGIC III
Canon’s new DIGIC III image processor drives improved responsiveness
and colour rendering along with increased noise reduction,
extending the camera's ISO range to ISO 1600. A dedicated
ISO dial makes it simple to switch between settings. Complementing
DIGIC III's performance, the camera features the same DDR-SDRAM
used in professional EOS cameras – raising the data throughput
rate substantially.
Face Detection AF/AE
For portrait and group shots, the PowerShot G7 is equipped
with Face Detection AF/AE, a new Canon technology that automatically
detects up to nine faces within a frame and sets the optimum
focus and exposure accordingly. If there is more than one
face in a frame Face Detection AF/AE is able to determine
the face or faces intended to be the main focus. The system
operates at the same speed as Canon’s established 9-point
AiAF system, which it automatically reverts to if no face
detection is required or intended.
Designed for photographers
Referencing classic rangefinder cameras, the ergonomic design
features analogue inspired controls, a multi-control dial
and a customisable shortcut button for faster access to
camera settings. Usability is further enhanced with a high
resolution (207,000 pixels) 2.5" LCD. The low-reflection
screen coating aids visibility in sunny conditions while
a wide viewing angle helps with group viewing or and aids
more creative framing options.
A selection of 25 shooting modes includes full Manual and
two custom settings, enabling users to tailor the camera
to their specific preferences. Shooting modes are complemented
by advanced settings such as AEB (auto exposure bracketing),
focus bracketing, and an integrated neutral density (ND)
filter with 3 stops adjustment. Photographers can also take
advantage of second curtain flash synchronisation for creative
flash exposures, while interval shooting (up to 100 shots
in 1-60 minute increments) allows for extended time-lapse
photography of up to four days.
Advanced movie functions include high resolution XGA (1024
x 768 pixels) video capture with sound at 15fps. Users can
also record VGA and QVGA movies at a smooth 30fps.
A new Safety Zoom feature allows users to extend the camera's
zoom range without interpolation affecting image quality.
Images can be captured at up to 14x zoom with enough resolution
for lab-quality postcard (10 x 15cm) prints. Photographers
can also enable the Digital Tele-Converter3 feature for
added telephoto reach on every shot, without the reduction
in aperture typically caused by optical tele-converters.
Accessories
In addition to Canon Speedlite support, the PowerShot G7
is compatible with a range of optional lens accessories,
including wide (0.75x) and tele (2.0x) converter lenses.
A waterproof case allows for shooting at depths of up to
40 metres.

Technologies Explained
DIGIC III
Canon’s DIGIC III (DIGital Imaging Core) image processor
manages all of the camera’s primary functions to optimize
operating efficiency. Advanced image processing algorithms
deliver superb image detail and colour reproduction with
accurate white balance. Key improvements over DIGIC II include
markedly faster response times, advanced Noise Reduction
Technology and support for Canon's Face Detection AF/AE
technology. DIGIC III also enables the PowerShot G7 to support
DDR-SDRAM, effectively doubling data throughput rates for
even faster performance.
Optical Image Stabilizer
The PowerShot G7 uses a lens shift-type Image Stabilizer
(IS) system to detect and correct slight camera shakes that
can cause image blur. Minute vibration gyros detect lens
tilting caused by hand shake. These signals – up to 4,000
per second – are processed by a single-chip IS controller,
which discriminates between hand shake and intentional camera
movements. Shake signals are sent to the IS unit, which
moves one of the lens elements accordingly to deflect the
light rays and cancel out the effects of shake. For improved
accuracy and responsiveness, the moving lens element is
supported on tiny ceramic spheres. In addition to minimising
friction, ceramic spheres avoid some of the problems that
can affect metal spheres, such as thermal expansion and
magnetism. The PowerShot G7's optical IS allows photographers
to shoot at shutter speeds up to 3 stops slower with no
perceptible increase in image blur.
Face Detection AF/AE
Canon’s Face Detection AF/AE system automatically detects
up to nine faces within a frame before adjusting the focus
and exposure accordingly to ensure optimal results. It is
able to determine which faces are intended to be the focus,
while at the same time it can recognize and immediately
revert to the partnering 9-point AiAF system if no face
is intended to be the focus.
SR Coating
The SR (Small Radius) coating is used on lenses containing
elements that have a significantly smaller radius on the
back surface of the lens than on the front surface. The
coating is optimised for small radii and is designed to
maintain the highest resolution and colour fidelity possible
by dramatically reducing ghosting and flare, while virtually
eliminating chromatic aberration.
Digital Tele-Converter and Safety Zoom
Similar to placing an accessory lens on the front of the
camera, Canon’s Digital Tele-Converter adds a constant digital
zoom to every shot (1.4x / 2.3x). While optical converter
lenses cause a reduction in aperture and consequently require
a slower shutter speed, the Digital Tele-Converter maintains
aperture size, reducing the risk of image blur.
Safety Zoom protects the image from interpolation at high
levels of digital zoom, allowing users to extend zoom magnification
without sacrificing image quality.
