This is what I see. I guess you are not counting the very top bar which is only half a bar anyway.
So by your count, 1st bar, Sigma is slight better. 2nd and 3rd bar, Nikon wins by a decent margin.
Also I would point out that nowhere did Sigma showed the kind of resolution that 2nd or 3rd bar on
Nikon has. However, if you think the difference is not significant enough, that's fine too.
Exact focus point is different but the very top half bar (bar 0 ) and 4th bar are out of focus so
optima focus is somewhere between 1st and 3rd bar for both lenses with Sigma slightly favoring 1st bar.
I admit the the first full Sigma bar almost but not quite equals the Nikon 3rd bar -- but the exact FP could have been between 1st and 2nd Sigma bars?
My point is that until I see an actual test target shot at slight angle to correct for any minor focus error, the verdict is still out. That may indeed show the Plena with a slight edge and I will accept that. Until that kind of test however, I will say 1) it's fairly apparent the two lenses are quite excellent as is, and having to go to 100% to try and find gnat's eyelashes of difference is also relevant, and therefore, 2) I think what this really means is that from a practical imaging standpoint, there is little between these two lenses.
However, as I said before, were I to buy a fast 135, I would buy the Plena simply for simplicity of color consistency and upgradeability, and being dedicated Z mount. (See, I'm still a Z fanboy too after all!)
Here ya go:
Sigma on A1 (slight resolution advantage) and Plena on Z9
Geez, if I photography my friend at f2.8, it could be very bad for my health
