The lens construction seems to be the same with the 12mm f2 NCS CS (manual focus lens), but the published MTF curves differ in areas. Whether that means the MTF simulation software has evolved over time, or that the optics are different in detail, I don't know. The Fuji AF lens does have the exact same optics as the Sony AF version. So, you should be able to determine if it performs well enough.
