Hasselblad is not holding back at the start of the year and has just released the smallest digital medium format lens ever. The 45mm f4 prime wide-angle lens is 320 grams and 47mm deep.
Designed for the Hasselblad X system, the lens has autofocus and two aspherical elements. Like some of the previous X system lenses, this one also has a leaf shutter to enable flash sync speeds of 1/2000s. It also incorporates a mechanical focus ring for that smooth manual focus experience.
Hasselblad is also claiming quieter autofocus which should make this a nice setup for intimate cozy environments. The lens costs $1099 and will ship at the end of January.
