I'm fairly new to LR, and I'll admit I have a lot to learn as far as post processing. Those caveats lead to my question- I've noticed some horrible CA with shots from my E-M1 when I drop the exposure and highlights in certain underwater scenes shooting up towards the sun. I've noticed it with the 9-18 behind a dome, and with the 12-50 behind a flat port- both with different shutter speeds. The example below was shooting up through some pilings at the sun with the 9-18, and I'm having difficulty removing it in post. I'm guessing a lot of this is from trying to recover too much from the (intentionally) blown highlights, but I don't remember it ever being this bad with my E-PL2- is there something unique about this problem with the E-M1? The bummer is that I also notice it at 1/320- that's the max sync speed, and one of the reasons I wanted to switch bodies in the first place. Any thoughts?
