in sigma's own words...
"Sigma has developed an integral-lens compact camera with the specs of a full-size, high end SLR. In other words, the DP1 has all the functions of a full-spec digital SLR, packed into a compact camera with a built-in lens. Here at sigma, we focused all our resources on achieving the nearly imposible. Sigma is not about creating run-of-the-mill photographs, or pursuing image quality defined by numbers. We give you a compact camera with the potential to capture exactly what you see and what you feel, with no compromize."
hmm....
does seem like it's got all the features of a dslr - but fixed focal length lens....

The sample pics are quite nice. Can't believe that the pics are from a camera which I think is a normal compact, which in reality is a compact with DSLR size sensor.
