Carsten You are absolutely right. The macro mode of that little camera is amazing. This picture is done with the LG-1. You can even see its reflection in the picture, I think ;) . I didn't know about the FD-1. I think I will buy it as well, because the main reason for buying a TG-4 was underwater photography. Thanks for pointing me to that!
Kazzi now I see that reflection. FD-1 was just announced, and knowing that was the reason why I commited my comment ;)
Kazzi TG-4 has wonderful macro mode. Have You seen LG-1 and FD-1 flash diffusers? They are not too expensive and do incredible work :D
