And in the two images of the iron fence, assuming you were carefully focusing on the acorn piece in the center, the 35/2 'acorn' is sharper or has more contrast.
Look at the Fuji MTF curves. The 15-er and the 45-er- are more near to each other as it is with the 1.4/35mm; and the 45er is nearer the 1. So the f2 should be more contrasty, if I understand the right way.
But, nothing you cant fix in post production Lightroom.
