Just compare the way the sagittal and meridonal MTF curves do diverge towards the edge of the frame - or rather how they do not diverge on the Canon 135L. There is a direct correlation between this property of the MTF chart and the bokeh...
Yup ... the Siggy has higher mtf, but not as tight between the sag & mer. The tighter the better. Not a terribly drastic difference here (compared to some that fall apart), but about as much diff in MFT toward Siggy as there is diff in sag & mer toward Canon.
As with so many things in optics, there are diametrically opposing attributes where you are trading one thing for another, so it comes down to a preference for the differences ... moreover, than claiming a superiority of "better", when you realize the inherent trade-offs that are in play.
The real take away here though (imo) ... nice to see Siggy get in the game of better optics than their legacy of yore has been.
