Here's my quick sum up of Amatuer Photo magazine's review as i said i would do, gave the G2 an 85%.
They seemed reluctant to rate it higher than 8/10 in all their criteria, except dynamic range where it scored 9/10 and autofocus where it scored 28/30 (the reviewer was very impressed with the touch focus area select and touch shutter feature).
The review liked how well the 144 zone metering system performed in tricky situations and liked the image quality - he said the slight straight curve (compared to other brands s curves) helped keep blown out highlights to a minimum and that the camera resolved a great amount of detail, he also liked the natural look of jpegs. Also he was impressed with how responsive the touch screen was, so sensitive the g2 would take photos if the screen was accidently touched.
Not really many negatives apart from... noise levels in comparison to other aps-c sized sensors. however he did comment saying that noise is only really obvious at iso 6400, at which in well exposed areas it isn't a problem, whilst in underexposed areas cyan and magenta patchs of noise appear.
