Just Posted! Our review of the Sigma DP2. Sigma was the first company brave enough to put a large sensor in a compact body and its DP1 was an interesting, if flawed creation. The DP2 is its second attempt - featuring a 41mm equivalent F2.8 lens and a series of improvements derived from the company's experiences with the DP1. However, it is no longer the only compact camera claiming to offer 'the power of DSLR' so can the DP2 see off the interlopers and does its unique sensor design give it hidden depths?
