Sigma had some pretty cool announcements today...check out dpreview.com
That DP1 looks like a slick compact camera especially with the squred hood attached. Foveon sensorific.
The 18-200mm IS lens looks like a good choice for those of you (Ian?) with an SLR and don't want to deal with a bunch of lenses.
But did you see the size for that 200-500 f2.8? Holy crap!
