The RC2 got one good addition - purple-green fringe removal tool. It actually works very well for the Nex bodies removing the purple ghosts in the corners/edges often seen with native lenses at 16-18mm.
P.S. But, as always, they did it just a little bit wrong. The fringe colour range to suppress is set in the output colour range/space, i.e. it is WB-dependent. So if you change the WB, you have to readjust the range. That's some really brain-dead approach, simply since the true input ranges are equipment-specific, so we could simply have some fringe-removing presets/profiles for a given body/lens combo, instead of doing per-image adjustments.
