It looks like the Yongnuo YN 50mm f/1.8 X DA DSM PRO for Fujifilm X is coming soon, so much so that some website are already sharing their launch pages including additional information and images, as you can see down below.
The new lens uses 11 groups of 14 lenses, including three low dispersion lenses (LD), four aspherical lenses, etc., to ensure the overall lightness and compactness, while also showing excellent imaging capabilities; the aspherical lenses are added to effectively eliminate the aberrations, spherical aberration, aberrations and other problems caused by spherical lenses.
Aspheric lens: effectively eliminate the aberration, spherical aberration, aberration and other problems caused by spherical lens, so that the surrounding incident light more ideally concentrated to the focal plane, and can save the lens, facilitate the lightweight design of the lens.
Low Dispersion Lens (LD): Effectively eliminates chromatic aberration and better suppresses dispersion problems.
It will cost 1799 Yuan (250 USD).
