And there it is:

From a sharpness perspective, the result is staggering (albeit only on a 5D3):
"Honestly, what I am supposed to write here? My admiration scale ended with the Sigma A 1.4/85 and the results of this lens are even better…Let me word it this way: if the Sigma in the frame centre performed as well as on the edge of full frame I would still enthuse about what a brilliant lens fell into my hands."
Later, in the summary: the Sigma wide open in the corners was sharper than the 135L was in the center of the frame at its sharpest aperture.
AF also looked good:
"In studio conditions, where we use mainly the central autofocus point, there were almost no problems with the accuracy of the mechanism, with the number of misses never exceeding 2%. Sample shots outside were a bit a different story as I used side points of autofocus quite often. I didn’t notice any big mistakes but, with a shallow depth of field by f/1.8-2.0, even a small slip-up might be annoying. From f/2.8 upwards everything returned to norm."
But it's far to early to tell if with the AF we have an 85 Art here (good) vs. 35/50 Art here (infuriatingly, randomly bad). Let's hope for the former, of course.
