A French magazine Réponses Photo has leaked the long-rumored Sigma DP2, which features a 24.2mm (40mm equivalent) f/2.8 lens.
This looks legit. Hopefully Sigma has addressed some of the criticisms of the DP1 (poor LCD, LCD freeze, long shot to shot time). The lens speed and angle of view should be well received.
