No, it is not the same lens at that of the DP2 Merill, not at all in fact.
No element is the same, and the DP2 lens is an 8 element, 6 groups design (with 1 aspherical element) where this 30mm f2.8 for Sony NEX/MFT is a 7 element 5 groups design (with 2 aspherical elements).

Indeed, you are right. I must have been fooled by same aperture and focal length; both 30mm and 19mm are different from DP2 and DP1. It seems (for the first time?)that Sigma decided to keep something good just for themselves.
