Actually, according to Photozone, even the corrected JPGs show .8 EV of vignetting wide open.I have an X100T and vignetting and distortion isn't an issue at all. It's all corrected in camera.
Anyway, I pointed this out as the OP was asking about the IQ of the lens. For some people, the raw performance is important. After all, pushing the edges 2 EV when the ISO is already high, or shadows are being lifted in a raw file, will result in more visible noise.
