Canon PowerShot G5 Review, Phil Askey, July 2003

Review based on a production PowerShot G5
The PowerShot G5 was announced at the beginning of June
2003, it is the five megapixel 'companion' (it doesn't directly replace)
to the four megapixel PowerShot G3 (which wasn't called the 'G4' because
of the similarity between the word '4' and 'die' in certain Asian languages).
The difference between the G3 and G5 are limited to:

How much bigger?
Resolution upgrades and if they make sense:
- Two to Three megapixels - 1,225,728 more pixels - 64% increase
(Average)
- Two to Four megapixels - 1,951,488 more pixels - 102% increase
(Good)
- Two to Five megapixels - 3,118,848 more pixels - 162% increase (Very
good)
- Three to Four megapixels - 725,760 more pixels - 23% increase (Not
worth it)
- Three to Five megapixels - 1,893,120 more pixels - 60% increase (Average)
- Four to Five megapixels - 1,167,360 more pixels - 30% increase (Not
worth it)
Thus if all you're interested in is increasing resolution (not necessarily
for features or other image quality improvements) you must first analyze
just how much more resolution you're going to get. From the quick calculations
above you can see that four megapixel digital camera owners should wait
for the next big leap (seven / eight megapixels).
Review Notes
Because of the similarity between the G5 and the G3 (they're
almost identical apart from resolution) the first half of this review
(body, operation, menus etc.) is based on my G3 review posted in December
2002.

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.
