I'm considering an NEX-6 for travel shots because of its small size and versatility. The kit lens looks fine for "walkaround" shots from what I've read. I'm also looking for a lens for lower light indoor shots that I can also use for rare concert shots. Will the pending 20/2.8 work well? The reason I ask is that my daughter will be in the 3rd row for a once-in-a-lifetime concert she has tix for. I've read that the live-view AF is too slow. Is the AF using the EVF fast enough for indoor/lower light shots with a 2.8 lens? Thanks for any recommendations.
