Hasselblad X-system mirrorless medium-format mount, introduced in 2016 | 43.8 x 32.9 mm digital medium format
XCD is Hasselblad's short-flange mirrorless medium-format mount. It was designed around the same 43.8 x 32.9 mm sensor class used by many modern digital medium-format systems, but in bodies much smaller than traditional modular SLR platforms. The mount appears on both integrated X bodies and the 907X camera interface, which gives the system a bridge back to Hasselblad's modular habits.
XCD lenses include integral central shutters, preserving a key Hasselblad working style while shrinking the camera system. That keeps high-speed flash synchronization available for location portraiture, studio lighting, and quiet handheld work without returning to a large H-system body. Adapter support for H, V, and XPan lenses also makes XCD a hub for several Hasselblad-era optical traditions, even though native XCD designs are autofocus digital mirrorless lenses.
The optical challenge is substantial: large image circle, compact barrel expectations, high-resolution digital capture, autofocus, and in-camera/software correction all in one package. In the catalog, XCD designs are a useful modern mirrorless counterpoint to both Hasselblad H and Fujifilm G lenses.
Flange focal distance 18.14 mm, bayonet mount. 0° at 12 o'clock from the camera front; the lens-side view is the horizontal mirror. Dotted strokes mark photo-scaled or schematic (not-to-scale) dimensions.
