We've been waiting for Sigma's DP-1 digital camera for approximately 18 months. First announced at Photokina in September 2006, it has been withheld from the market through what Sigma describes as "unforeseen image quality problems which resulted in a requirement to change the specification of the camera's imaging pipeline". But it's here now - and a very interesting camera it has turned out to be.
The DP-1's metal camera body is sturdy with an angular styling and clean lines that are reminiscent of Ricoh's GR Digital models.  Although the dimpled areas on the front and rear panels are well positioned, we'd have liked a slightly better grip. A small moulded protrusion would have provided greater comfort and (perhaps) allowed a few more components to be packed into the camera. Unfortunately, the plastic lens cap supplied with the review camera didn't match its build quality and couldn't be used when the lens hood was in place. You can read the whole review here and you can buy the camera here.
