>>3447559>>3447560green bokeh is exacly where you look for microcontrast, and it is poor. No wonder they weren't allowed to put Zeiss sticker on the lens.
Not a big issue for the system really, that other 135mm that they have has pretty good contrast. Morons and gearfags will buy this one, smart ones will go for sonyzeiss. It's just a bit pointless lens really. Bit faster, but at that focal length you really don't need anything as fast, and sharpness is equally irrelevant for bust to face portraits, since everyone is photoshoping everything away in the end.
