See my Hasselblad X1D wish list.
The about $3995 Hasselblad XCD 30mm f/3.5 is equivalent to a 25.4mm f/2.87 as compared to a 35mm full frame camera (long dimension of frame). It is thus a solid wide angle choice—not super wide and not moderate, just right for many purposes.
The Hasselblad XCD 30mm f/3.5 for the Hasselblad X1D looks to be a very fine performer, but with a key behavior that every X1D shooter should be aware of.
This series at MOD (minimum object distance) assesses overall sharpness along with focus shift and secondary color aberrations.
Includes images up to full resolution as well as large crops, all from f/3.5 - f/11.
