MTF for Fujifilm GF 30mm f/3.5 R LM WR
Like most brands, Fujifilm does a lame job at publishing MTF charts—wide open only, and no description of the spectral balance for the claimed performance, and it looks to be diffraction-ignoring computed fantasy MTF to boot—not measured with a real lens.
Overall lens contrast for coarse structures is exceedingly high wide open. Contrast of medium structures is exceedingly high (and not very believable!) in the central 1/2 or so of the frame declining somewhat in the outer zones together with quite substantial astigmatism, which might be lateral chromatic aberration (which gets corrected as a requirement as per the image EXIF).
