Canon PowerShot G2 Review, Phil Askey, August 2001

Review based on a production PowerShot G2
Canon unveiled the original PowerShot G1 just before
Photokina last year (September 2000). It took quite a few people who were
expecting a Pro70 replacement by surprise. The G1 immediately struck a
chord with people considering Nikon's Coolpix 990 or Olympus's C-3030Z.
And here we are just less than 12 months on with the next evolution, the
4.0 megapixel PowerShot G2.
The G2 is based on the same 'prosumer compact camera'
form factor with an almost central lens, viewfinder window and right-handed
flash unit. Immediately obvious this time around is that Canon realized
the little 'blip' of rubber on the G1 wasn't enough as a sensible grip,
now we get a fully moulded (though plastic and a little thin) hand grip.
The second most obvious change is the colour. The camera is done out in
a kind of 'three tone' - the front is champagne coloured magnesium alloy,
the center (top / sides) silver plastic and the rear a kind of metallic
painted silver plastic.
The G2 features the same extending 3x, F2.0 - F2.5 'Canon
Zoom Lens' (which I'm assured is made by Canon) as we saw on the G1 and
the ring surrounding the lens can be removed to take the optional lens
thread adapter, required to add optional wide angle, telephoto or macro
lenses.
Here's a quick breakdown of the primary differences between
the PowerShot G1 and G2.

It's good to see that Canon have been paying attention to G1 owners complaints
and solved some of the problems it had. Especially noteworthy is the new
Evaluative metering system and the ability to select one of three focus
points (I can imagine the sighs of relief on our Canon Talk forum as I
write this).
Review notes: Products shots / menu captures were made on a pre-production
G2, final review was completed (image quality / comparison / features
/ samples) using a full production G2.

If you're new to digital photography you may wish to read the Digital
Photography Glossary before diving into this review (it may help you
understand some of the terms used).

Images which can be viewed
at a larger size have a small magnifying glass icon in the bottom
right corner of the image, clicking on the image will display a
larger (normally 960 x 720 or smaller if cropped) image in a new
window.
To navigate the review simply
use the next / previous page buttons, to jump to a particular section
either pick the section from the drop down or select it from the
navigation bar at the top.
DPReview calibrate their
monitors using Color Vision OptiCal at the (fairly well accepted)
PC normal gamma 2.2, this means that on our monitors we can make
out the difference between all of the (computer generated) grayscale
blocks below. We recommend to make the most of this review you should
be able to see the difference (at least) between X,Y and Z and ideally
A,B and C.
