So got the adapter. I did a quick test, putting the adapter on didn't seem to change IBIS behavior, and from what I can see, didn't change exif info either.
I don't have the GW-4 lens yet, so can't text to see if it changes anything. Maybe it has to be switched on manually somewhere? Because I definitely saw some people on flickr that had 13mm in exif info instead of 18mm. No idea.
Few quick pics. 1/10 I can get a sharp image, 1/8 can't (or need to take pics to achieve sharp image). Seems 1/10 is as low as I can go with adapter and without.
No adapter - 1/8
No adapter - 1/10
With adapter - 1/8
With adapter - 1/10

Huh, I just noticed. There's a leaver inside of the adapter. Looks like when GW-4 is screwed in, it pushes the leaver down activating the contacts. I'm guessing the camera then knows that GW-4 is installed and changes whatever settings (if only the exif info). Pretty clever) I just hope the cpl i purchased won't push that leaver, it's recessed pretty deep in the barrel of the adapter. Fingers crossed.
