I own the "Canon G7", therefore, I empathize with your whole solid review of your "Canon G9" - I did think long and hard on selling it on ebay to upgrade to the G9 after reading all the very positive professional and amature reviews - (were all excellent).
Your review of the G9 is certainly one of the more honest and balanced reviews by an owner Ive seen yet on amazon.co.uk or amazon.com, its concise and gets to the point without adding fiction. Yes! its true theres only certain limitations with any top of the range pro compact (non DSLR Digital camera) at (ISO 800 and below)), the G9 I must say in my opinion number one for the time being here at the end of the year in 2008. (very well built) no other camera in the pro-sumer point and shoot market can touch the sheer quality and workmanship of the G9 and G7.
I have decided however to hold on to my Canon G7 and instead invest only an extra £80 odd quid, and purchase the new Canon EOS1000D 10MP CMOS DSLR With I.S KIT Lens, as here on amazon.co.uk at time of this review I can buy for only £349.99 which taking into consideration the ground breaking technology, is an absolute bargain... Ive watch all the (best video professional reviews on youtube) on the EOS1000D and have decided to buy asap while it remains at this price (£349.99 with 18-55mm Canon I.S KIT Lens)- the bonus for me is the fantastic PC software that comes with the eos1000d the optical image stablization, 10mp Large CMOS sensor, together with canon's own Live view 2.5 inch screen. The main attraction for me is advantages like (noise and grain free) images at very high ISO's 1600, territory out of the G9 league, and any other "top of the range - digital compact camera".
I will be holding on to my G7 and recommend anyone looking for a (pro-sumer point and shoot solution) with many DSLR features, solid build, razor sharp images (at ISO 800 and below), buy the Canon G9 if you dont already own a Canon G7!
J.Francis, thanks again for a very interesting review on your experience with your Canon G9. 5 Stars! *****
amazon.co.uk is best on price, and next day del on the G9 at present.
