Now this is cause for concern. Hope I did something wrong, or else I'd say my copy of the Batis 40 has some serious issues. It seems to be sharper in the edges of the frame than in the centre. I redid the test image three times, and manually focused it on the last round to make sure focus was spot on in the centre. Or maybe the FE 50 is just that good. I'm definitely not happy with the centre-performance of this Batis 40 though.

Left extreme looks identical for both lenses to my eyes. But the centre-performance of the Batis certainly looks wonky.
EDIT: I don't know what went wrong here, or how - since I redid these tests three times, but something must have. Extensive tests after this have shown that my copy of the Batis 40 is not as bad as these images may indicate. I'd say the centre-performance at F2 has some variation depending on distance, though. Certainly all of my actual use of this lens in the field has shown excellent results for sharpness, so I'm writing this off as an abberation.
