Hi Dave,
nothing wrong with your snapshots! The XA2 is the camera to take along for these kind of shots if you don't want to take a camera along (does this make sense? I guess you know what I mean)..
That said, there's a couple of things I found that have big impact on my XA2 images..
First, there's the aperture versus shutter speed thing.. I find the XA2 has a preference for slow shutter speeds, and rather closes the aperture down too early to get more DOF. Probably this is to cover for having only 3 distance settings that don't overlap in DOF at f3.5.. The result is that a lot of images I shoot have motion blur (or camera shake) when there's not a lot of light.
Then, there's the choice of distance settings.. The snapshot mode at 2.4m (8ft) is precisely that; a snapshot mode, but to my taste it's too close for a 35mm lens. When I shoot 'from the hip', I prefer to have the distance set at 100x the focal length. With that rule, you can fit a person in the frame for any given focal length. That would be 3.5m (12ft) for the XA2's 35mm lens, and not 2.4m.. When you're having people full length in the frame, infinity is a better choice than the middle distance setting. I've taped a reminder under the viewfinder so that I don't forget the camera resets to middle distance each time the clamshell is closed.
But these are only minor quibles, because if I keep the above in mind, the XA2 is able to produce incredibly sharp and detailed images.
