Thanks Denis for posting this helpful bit of information. Did you get it to work after all? I just came off a shoot with my EX-1 and a rented EX-3. Silly me, I just assumed I could store my camera settings from my EX-1 on an SxS card and recall on the EX-3. I’m amazed how little design gotchas like this can create extra stress in the field. Facing more time and $ for color correction in post. Sure would be nice if Sony could make this a uniform feature between cameras. I hope this info can help someone else who is prepping a shoot with these two cameras. .suf files, who knew!
