I'm considering an NEX6. In addition to the kit lens (which would handle outdoor, walkaround), I'm looking for recommendations for a lens that would serve me well for indoor, family shots. It would need to be wide and fast enough for indoors. My concern is whether the 35/1.8 is wide enough for indoors, or whether or not I should go with the 16/2.8 (or pending 20/2.8). To add to my uncertainty, my daughter is going to be in the 3rd row of a concert in August, and I'm assuming cameras will be allowed--I'm going to double-check. I'm hoping the lens I decide on will be wide and fast enough to get some shots from the 3rd row. I'd appreciate any recommendations.
