From Roger Cicala at LensRentals:Every so often, though, I get to see an internal design that is so elegant and efficient I think the engineers should have signed it like a painting. The Sony NEX cameras are that way. Perhaps being so small required efficient engineering, or maybe the team that designed it just was so good. Maybe the fact that there was no legacy technology that was cheap to carry over to the next model let the engineers, rather than the beancounters, make all the decisions. Whatever the reason, the layout is amazing.
