medium wide to wide (same lens as X100)
23mm f1.4 best but prefers 23mm f2

At close to medium distance, the XF23mm f/2 does exhibit barrel distortion along the edge (more so than the XF 23mm f/1.4mm) as well as some softness.
Although this lens performs well while shooting wide open (AF speed and accuracy), optically the lens performs best at f/4-5.6
