Everybody, finally we can understand the differences between a lens labelled Carl Zeiss Sonnar T* 2.8/135 and a lens labelled Yashica ML 2.8/135mm
Today I have made a test 1/500 at f:8
Carl Zeiss Sonnar T* 2.8/135mm

the crops!
On a 21 megapixel digital camera the differences are more visible!

Zeiss slightly better along the edges, as it was to be expected.
Center performance is identical to my eyes. Zeiss maybe just a tiny bit contrastier.
P.S. Yashica shot is slightly front-focused.

I see better clarity & microcontrast for the Zeiss, the metals shine more and the walls are cleaner
but I don't expect that 2 lenses at F8 will show lot of differences
if you check this more scientific test, ML & T*, you will see that differences should be more visible at F2.8

Yes, the Sonnar is definitely better, but also you have to look at the price difference and consider that too. I don't think the ML is bad for a lens that costs what it does as compared to the Zeiss lenses, but the Zeiss lenses were the top of the line and you paid considerably more for that, still do. If you can afford the Zeiss, sure, go for it, but I actually think the ML looks pretty respectable considering it's the "middle" lens in terms of quality, though honestly I don't think the DSB/YUS is bad to start with. It's like the difference between tourist class, business class and 1st class. Each one has it's purpose, and it's price tag. You want leg room and champagne it's 1st class all the way, but if you can't afford that and still want to be able to breathe at least, you fly business class.

Poilu nailed it in my opinion: at f/8 in the center all lenses are good (except for some AF trashbin stuff). The challenge is wide open.

Guys, that's f/8 for Christ sake! Try 2.8 or 4, add some background, and watch the in-out of focus transition closely. The Zeiss is by no means APO, but it shows way less loCA than the Yashica lens.
