I shall be looking forward to any DP images ! What is it that makes this little camera so special ? I don't have a DP camera, so I can't tell.
Aha - found you Dave! Flickr: chelseadave55's Photostream I almost grabbed that shot of yours from your London set "me bigger than st pauls" but felt that might just be overstepping my bounds a bit.
There does seem to be something special about the Sigma's images. Maybe it is its "soul"?
I have asked a Flickr pal of mine who goes by the name of vaquey Flickr: vaquey's Photostream, if I might link to his stream and some photos here. He has very kindly given me the go ahead. Unfortunately I am not able to post his photos or grab links to embed. I highly recommend his photostream!
