Hi Herman, the DP cameras produce exceedingly clean files with high dynamic range (retained highlights, open shadows) and smooth tonal transitions which are resilient during during tone mapping (pushing, pulling). The lenses are sharp and well corrected (especially DP1 which is sharp corner to corner wide open) with high microcontrast, and the sensors produce beautiful if not accurate colors. The low ISO color image quality is the best, from my perspective, that I have experienced in a pocketable camera. Black and white results are also excellent, whereas high ISO color results are not so great, especially with unbalanced lighting.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!
