At first glance the G10 is almost indistinguishable from the G1 or G2. It has the same relatively compact SLR-style body, made from tough resin plastic over a metal frame. The build quality is excellent, with tight panel joins and strong secure hatches. The matt surface provides plenty of grip and resists marks and scratches surprisingly well. Unlike the other models in the G-Micro series, which are available in a range of colours, the G10 is only available in the matt black finish shown here.
The control layout is also very similar to the previous models, with a chunky main mode dial on the top right panel and a smaller AF mode dial on the top left. However a closer inspection reveals a few important differences, the most obvious being the monitor. It is still an impressively fast and very sharp 7.5cm (3.0 inch) 460k TFT LCD screen as before, but where the G1 and G2 (and indeed the GH1) have articulated monitors able to flip and twist around a side-mounted hinge, the G10 has a fixed screen like the GF1. In most other respects the control layout is identical to the G2, with the rear-mounted control wheel (it was on the front on the G1) and a dedicated illuminated button for the iAuto mode. The only obvious difference is the lack of a dedicated video recording button.
Another way in which the G10 differs from its more expensive siblings is the electronic viewfinder. The G1 and G2 have excellent field-sequential displays that provide sharpness almost as good as an optical TTL viewfinder, but the G10 is equipped with a cheaper standard TFT LCD display viewfinder, with a resolution of 202,000 dots. It's not bad, with decent colour and a fast refresh rate, but it's nowhere near sharp enough for accurate manual focusing, even though it does automatically magnify the view in manual focus mode a soon as the focus ring is moved.
