Yeah i love the vertical spin, i have seen some really cool shots done like that. But that's interesting to know about the weather. Though I live in Australia so i doubt that will be too much of an issue :P I did read somewhere about someone buying a larger ring for theirs (i guess for this very reason) that had a link to which one they bought. I'll go hunting and will post to you if I can find it again.
When it comes to film speeds are you using the recommended 400 ISO or are you going slower on the cloudy setting? Curious about what can be done with motion blur on this camera.
