Another day, another super-speed lens promised for X-mount. This time, however, that lens comes assembled in the fatherland. Thanks to X-mount's APS-C sensor, this hulk of a lens (680g) will achieve the field of view and depth-of-focus similar to that of a FF ~50mm f/1,4 lens on a FF camera.
Small sensor cameras can be small. Equivalent lenses never are.
