Fujifilm has patented a new XF 16mm F1.8 wide-angle lens designed for APS-c size sensor X-mount cameras.

The new wide-angle prime optic would be the f/1.8 version of the current XF 16mm F1.4model. It is effectively a 24mm lens, when mounted on an APS-C sensor X body.

From the patent application the optical design of the XF 16mm F1.8 is similar to the f/1.4 version.  We guess that this might be a budget-friendly version of the bright aperture one.
