My experience with the MC20 teleconverter with Oly 40-150/2.8

So I got really lucky... just today the ordered Olympus MC-20 teleconverter arrived. Although its raining and we once again enjoy one of those overcast darkgrey terrible light conditions I needed to do some tests...
Roundup: I'm pretty impressed by the combination. AF on G9 is a little slower than with the MC-14 converter on or with the lens only (no surprise there). The AF is still pretty fast and I expected it to be much worse.
To actually use the teleconverter on the lens I needed to update the lens' firmware first. Fortunately there is a special firmware version of Olympus lenses for Panasonic bodies available here:

Unfortunately DxO Photolab 3 doesn't provide a correction module for 40-150/2.8 + MC-20, which is a bummer. Even worse, in the focal range between 80mm and 150mm DxO Photolab interprets the photo as shot with the Oly 40-150 lens only and hence provides a false correction module. Well, well, lets just hope they will deliver the proper module sometimes later.
Other than that so far all I have to show is some standard test photos right out of the door (wifey's decorating the xmas tree in the living room - need to hurry ^^). Please excuse the limited creativity in the photos... tests only!
Postprocessing: slight denoise (PRIME) and sharpening within DxO, followed by Topaz AI sharpen (which offers denoise also). Photos are fullres, incl. exif data. All handheld.
Hope its of help to anyone out there hesitating about that combo.
Cheers and merry xmas to all.
