This is the newer 45mm compact version-in short supply but we have just received one from Hasselblad Australia-
The XCD 4/45P is the world’s lightest digital medium format autofocus lens on the market today, weighing 320g (0.7 lbs). Its compact, lightweight build combined with world class optics makes it the perfect lens for travel, exploration, and documentary.
As the most lightweight member of the X System lens range, its size perfectly complements the compact
X1D II body. Like the other XCD Lenses, the XCD 45P has an integral central shutter offering a wide range of shutter speeds and full flash synchronisation up to 1/2000s.
