he lens consists of ten elements in six groups, including two aspherical elements. The optimum positioning of the aspherical elements ensures flatness of the image plane for edge-to-edge sharpness. The aspherical elements are used as part of the focusing group to minimize performance fluctuations between different focal distances.
he inner-focus AF system uses a stepping motor to drive lightweight focusing elements for silent and fast autofocus. When combined with the phase detection AF system of FUJIFILM X-Pro2 and X-T2, the lens can focus in an astonishing 0.05 seconds.
The lens barrel is sealed to make it weather and dust resistant, and capable of operating at temperatures as low as -10°C.
When mounted on the weather- and dust-resistant mirrorless digital cameras FUJIFILM X-Pro2, X-T1, and X-T2, you can shoot in light rain or a dusty environment with peace of mind.
