Excerpt: So, I took my a3000 out for about an hour of shooting. I won't make this a full-fledged review, just a few major points and one major issue. I just got mine delivered yesterday, so haven't spent much time getting to know each other. (yet). First, I've not ever used a translucent mirror camera before. So, having no optical viewfinder is driving me crazy on a harsh/overcast day.
Summary: The A3000 is definitely a step forward from the smaller NEX bodies and outperforms them in some aspects including response. In terms of video quality I can confirm what another reviewer referred to as "fixed patter noise" to be an issue. It's most visible in dark areas or when a shot is out of focus. The video also has more artifacts than the NEX or alpha cameras.
Summary: I won't go into all the features because you can find that information elsewhere. Upon picking up the camera, the first thing I liked was the feel. It's the perfect sized travel camera for someone used to a bigger DSLR while having a comfortable, deep recessed, rubberized grip. The included 18-55 zoom feels mechanically solid for a kit lens, and it's also fairly sharp corner to corner. There's very little geometric distortion or chromatic aberration.
