Looking at drastic recovery from intentionally stuffed up SF jpeg files from the EM1.
The top row is recovered form +2.5 stops. The colour shift (CA from the 25mm?) is ugly in the original, but fixable and the file is clean.
The bottom row is interesting though. Nice recovery from -2.5 and very little noise (ISO 400 exposed at I guess about 1250)
Closer detail of the shadow recovered one. Again the sharpness is pleasantly natural, not over done.
At about 700x600 px or “not big enough to fill a post card” size. Impressive clarity, noise control and recovery. Sure it is a bit crunchy, but those are actual pixels you are looking at.
