I gotta be honest shooting with the GA645 is a bit like cheating! Automatic focus and exposure. I also brought my FUJI GW690III to Iceland but it rained everyday so it was hard to use it. In fact most of my shots that you see on here with the GA645 were taken in rain or just before or after rain. I did manage to shoot about half a dozen of photos with the GW690III so I will post those sometime in the future.
