... the DP1 is hardly a cheap compact, in fact it costs more than a DSLR, but it is a unique proposition both in terms of its design and its sensor. There are other cameras with similar handling, but the sensor size is sure to appeal to a certain type of photographer. ..."

... It's hard to discount the smooth beauty of the DP1's output, thanks to both the well-designed Sigma lens and the refined output of the Foveon X3 sensor. But the slow autofocus, difficult interface, and slow post-processing required to achieve that excellence is hard to ignore. ..."

... The Sigma DP1 is certainly a specialist item designed for those to whom image quality is their key requirement. It's aimed at the professional and advanced amateur image-makers who want the quality it can provide in a pocket-sized bundle. The camera is simple and robust with no pretensions to being pretty, but it is practical with a sensible interface that's not full of fairy-ware!"

... But that's all past now. We've got a full production version of the DP1 and it is heading to the Pop Photo lab as we speak. But I couldn't resist stealing it away for a 24-hour whirlwind tour. Was it worth the wait? We'll have to wait for the final certified test results to make our final verdict. But I'm ready to share my initial findings on the shooting experience, feature set and handfeel ..."

... Under the right circumstances the images from this camera can be quite stunning. Noise is low even at ISO 800. Shadow detail is good. Dynamic range may be a little less than most DSLRs, so maintaining highlight detail is more the challenge. Color, contrast and sharpness can all be easily optimized with RAW processing. I was also impressed by how well the images held up even with a lot of post processing in Sigma’s RAW program ..."

... Sigma's DP-1 is a revolutionary camera - and quite different from any other digital camera in the current marketplace. This, in part, accounts for its relatively high price tag and restricted feature set (prime lens, pared-down set of controls, limited video capabilities). It is not a camera for point-and-shoot photographers. Nor will it suit photographers who only shoot JPEGs and prefer not to become involved in subsequent editing. ..."

Sigma decided to use a fix focus 28mm f/4 lens. While this maybe a popular choice we would like to see a top 28-70mm f/4 zoom lens. Maybe to get a smaller lens the sensor could even be slightly smaller. Also the decision to have a good optical viewfinder (although optional with the DP1) is a good idea. ..."
