I'm pretty sure this is a debate forum.

I was thinking the lens design determined the motor count. They always come in pairs. My understanding is the 4 motor lenses moved 2 groups for focus. The size of the motors can vary depending on the size of the elements. I seemed clear the design goals involved good 120Hz focus ability and they will do what is needed to get this.

Focus speed and accuracy is just another design objective, I don’t care much how many motors are used.

Yes, let's wait for the outlier to prove itself in the hands of actual users

Not yet.
For me the decision comes down to AF alone (as I don't think I will be able to tell the difference in rendering vs DN):
if it behaves like a (until now) 4-motor, then I will be tempted to sell my Sigma...

When people make simple basic statistical mistakes, I will point it out. Drawing inferences claiming they are from data when the data does not support those inferences is one of my pet peeves so you will see me comment on that from time to time. Some may find that useful. Some may not. If you don't like it, then feel free to use the hide me button.

For the sake of this thread, can you stop please?
Let's just agree to disagree

.
I only said "simple basic statistics" does not apply so easily here, because the samples are not independent.
Do you want me to get my stats book off the shelf

?
Maybe for you "simple basic statistics" means something other than for me. The same way you're happy with your hit rate with MF lenses (and 85DN) and I'm not happy with AF hit rate of what 50/1.4GM (and 85DN) present in demanding action.
It's not a "simple basic statistical mistake" on my part but what I infer from the past 5 years of Sony lens releases. Can I be wrong? Sure, but that's how the trend looks to me for now and I hope I'm allowed to say what I think here.

From my perspective, you see the trees, I see the forest.

It seems pretty clear what you gain with the II, but it is less clear what you lose. Is this I one of those lenses with such a magical rendering its shortcomings, including weight can be overlooked? That is the question (from someone who sold a Noct Nikkor for next to nothing before they became fashionable).

My only issue with the DN is focus speed and that is pretty minor. I find the 85DN too slow for sports. Other than that it is fine. I have the 135GM and 50/1.2 GM that I use for sports. So I think I’m OK with skipping the 85GM. The price difference would be better applied to a 70-200 GM II for me.
