Howdy!
Just in case somebody would know the owner of this camera:
A FB-friend of mine found it in a train between Helsinki and Turku in Finland on this date, which is September 4th 2013. The camera obviously belonged to a Japanese couple and it had pre-wedding and wedding photos, as well as travel shots taken in Finland. There were also pictures taken in Tampere (of the Moomin Valley) and in Tallinn, the Capitol of Estonia.
I don't have any more info about the camera, but I can of course ask the guy who found it.
So, if you know somebody who knows somebody who's lost a camera with quite emotionally important pictures, please pass the link to them.
Thanks!
