It's for Sony E and µ 4/3. Pity not for Fuji - these lenses would be an alternative to the f/2 series. The 19 and 30 is the same they also used in their dp merrill and the quality is great.
Not really... The DP Merril 30mm lens is more compact. And has 7 elements as opposed to 8 elements for the DN.
For the DP Merril 19mm lens: 9 elements in 8 groups, the DN 19mm 8 elements in 6 groups.
You're right :wacko: . Funny, my error came from the same FL of the 19 and 30 mm and I never checked the details. I just saw there's a DN 60/2.8 instead of 50/2.8 (and no macro, 1:7.2 vs 1:3).
