I'm curious how the overall camera feel on the G3 compares to the xda camera mod for the G2 (and other LG phones). The camera mod brings virtually all the new capture functions to the G2 that showed up in the G3 (of course, no laser focus, lol). The laser-focus is hard to grasp by just reviews though. People call it 'blisteringly fast' though I don't know what this translates to. If it's compared to the previous cameras on LG phones, it's not hard to get 'blisteringly fast' in comparison, as the focus on LG's cameras has always been broken. The camera mod significantly improved it, though there's still a little bit of lag.
TBH, re the OIS, I can't say I notice much improvement with OIS turned on or off on my G2. Curious how the G3 compares, since it allegedly uses the same correction method (afaik). Or perhaps they have a different algorithm/stabilization method.
It's roughly as fast as the other options out there so far, such as HTC's Duo Camera and Samsung's ISOCELL. It's not instantaneous, but it's quick enough that you won't be tapping the screen to focus unless the subject is really hard to find or very much off-center.
