The long-awaited and long-delayed Sigma DP1 is back at another trade show! First unveiled at Photokina in September 2006, the DP1 is now slated for a March release, priced at $1000 rrp or $800 street. The sample that I tried was still a little rough around the edges, but it looks as if the Sigma DP1 will finally see the light of day. Also being displayed was a new 200-500mm zoom lens, costing a whopping £16,000!!!
