I've now shot 3 motorsport events with my G3 and it's now the all-singing all-dancing camera that I never really thought it would be capable of being. 4 weeks ago I was an hour into shooting motorsport with it and realising that all those who said it would struggle with fast moving objects were right. Fast forward to today and it's now unrecognisable from that day. That said, it's taken me 10hrs of shooting to tweak the settings to a point where it's now operating at a speed that doesn't make me miss my Nikon D90. It's ironic, but Panasonic have been 'dumbing down' the G range and trying to make it more accessible to those moving up from compact cameras, yet for myself moving 'down' from a DSLR it took quite a bit of effort to turn it from a very average camera into something that I now think is brilliant. On the one hand it's brilliant that these bodies do have so much customization for those a little more serious about their photography, but at the same time the initial set up of the camera 'out of the box' really doesn't sell the camera as well as it could do. The most obvious example is AFC / AFS, read the manual and the first thing you would do is switch to AFC if you were going to an airshow (for example), yet it's far easier to shoot in AFS for objects moving over 30mph. I've found a couple of discussions on this on DPReview and other forums etc where they've come to the conclusion that AFS makes far more sense than AFC in most situations (the same goes for Single Point AF Area vs. AF Tracking) so I don't believe this is specific to my shooting style. I appreciate that fast moving objects (motorsport / airshows etc) are hardly the most common of subjects for the masses, but I'm sure there are times when many people find themselves in a situation where they might want to shoot something along those lines, I would hate to think somebody was struggling with their camera through no fault of their own, when a few quick tweaks could transform their camera into a tool genuinely useful at shooting some challenging subjects.
