I don't shoot much action, don't have an extensive collection of autofocus lenses from other manufacturers, and lately find myself reaching for the kit lens more often than not out of sheer convenience. What I do want : 1) High ISO performance that's at least the same or better as Nex-6 2) Auto ISO so that I could set minimal A and S and have the camera adjust ISO as needed. 3) Better focusing with my lenses. In the order of preference (a) less hunting in the dark (b) improved accuracy (do both cameras have eye detection and is it reliable ?) and (c) faster. 4) Reliable video. Nex-6 has been pretty solid with no overheating and I'd like to keep it that way with the new body. 5) Faster startup times with 18105 and Sigma 30. 6) Better capacity for cropping (larger sensor). 7) Ideally, better AWB. There's nothing wrong with my Nex-6, it's only got just over 18K actuations and can probably last me another three years. So it's more of "would it do me any good" thinking. The three most important reasons to upgrade for me would be 2,3 and 5, with 1 and 4 being the necessary preconditions. The second question is, would I get any benefit from using A6300 if I have no desire to use Canon or Nikon AF glass with adapters ?
