Just a quick look at a RAW and jpeg image comparison from the Pen F and 12-100 (at 100mm f4, supposedly it’s worst performing setting and hand held at 1/60th)
Standard, fairly mild pre-set for the RAW, nothing for the jpeg, then some mild brush work over the focus area.
The first of each is the RAW. Getting increasingly hard to tell. This bodes well for the jpeg based HDR, HiRes and other features the camera offers for landscapes.
