Well read the official press release and note this
引言回覆:
To achieve its compact form, the light projection of the lens has been designed for the ‘48mm full format’ sensor of the H3DII-39 and H3DII-50. At the wide-angle setting, in particular, Hasselblad’s designers have balanced improvements in lens performance with a slightly greater distortion and vignetting as these are eliminated by Hasselblad’s Digital APO Correction (DAC) without any compromise on quality. The outcome is a powerful tool that zooms from an impressive 83 degree, wide-angle to just beyond the fringes of a normal lens.
Which really mean they got acutance and resolving power by leaving the lens well uncorrected and simply had those done software. And the lens will not cover the 645 format film ... might be a good one for H3D user, but me, I am not interested in a lens that need software to actually properly image a photo
