I'm considering the purchase of a G1x, but am concerned about the AF speed, which has been reported as being glacial. I am currently shooting with an Olympus e-p1 with the 17mm kit lens, which is not fast by any stretch of the imagination. I prefer shooting wide open at the 28-35mm range, so I'm not concerned about the fact that the minimum aperture is so much higher at the long end. I do have two kids... One is 3 and the other is 6 months old. Most of of my photography today is focused on my kids, although I also enjoy shooting documentary and street photography.
I have used Canon cameras in the past, and I currently own and use a G7 (waterproof housing is great in the pool and at the beach!), so I am very aware of the image quality that comes with a canon product. I am also considering the eos m, although I would prefer the build quality and convenience of the G series cameras.
Any thoughts on this would be greatly appreciated.
