I am not sure there is a focusing difference but there may be
a focusing difference. On the Sony focusing was at live at 11X magnification while on the Hasselblad it was with optical viewfinder with a 3X monocular giving 9X magnification. Live view focusing is on the sensor itself, so it is as exact you can get. Focusing ground glass introduces tolerances.
The Hasselblad has an image size advantage, but the megapixel advantage was cropped away. The Hasselblad image is also a bit warmer.
As it turned out, I actually preferred the uncropped Hasselblad image, it was better balanced.
Maybe just me, but the Hassy files look quite a bit better. Factor in the focus difference and it's even more impressive
But hey, it's your camera and your images...
