After several tantalizing teasers and one very serious leak yesterday, the Hasselblad X1D, the world’s first compact mirrorless medium format camera, has officially arrived. Behold the promised “game changer.”At just half the weight of a conventional Medium Format camera, the X1D still manages to pack 50MP of resolution into a camera that can fit in the palm of your hand. The weather and dust sealed X1D sports a 50MP CMOS medium format sensor that promises 14 stops of dynamic range and an ISO range of 100 to 25600.
As you might have already guessed, the X1D uses a new line of lenses, dubbed XCD, with an integral central shutter. Shutter speeds range from 60 minutes to 1/2000th of a second and the system offers full flash sync all the way to that 1/2000th mark. At launch you have a 45mm f/3.5 and a 90mm f/4.5 lens to choose from, but all 12 H System lenses can be used with an adapter.
The camera also boasts a Nikon-compatible hot shoe, 3-inch 920K-dot touchscreen LCD, a 2.36M-dot XGA electronic viewfinder, integrated Dual SD slots, GPS, Wi-Fi, 1080/30p HD video capability, a USB 3.0 Type-C connector, and a Mini HDMI port.
