The compact interchangeable lens for the GFX mirrorless medium format camera system has a focal length of 35 mm (equivalent to 36–79 mm in the 35 mm format) and is particularly suitable for portrait shots in studio environments that are difficult to achieve with other medium format lenses. The bright f / 4 zoom with fixed aperture and a powerful OIS for optimising image quality are further product features. Changing lenses is easy, and the zoom and aperture ring is also convenient to operate.
