Are you planning to sell your 85mm 1.2 in antication of a new offering?

Uh, no.

Mine is producing great images and any imagined loss in resale value only occurs if I sell it.

No need to upgrade for the sake if upgrading.

and as another useless single data point, my 35 and 50 Arts both focus quickly and as precisely as the muppet behind the viewfinder allows them to in dark conditions

Compared to...what? 85LII focuses more precisely than the Sigma Art's on the 5D3/1DX and newer systems.

I don't collect lenses for their resale value. So, no.

I buy lenses to help me create images. All my current lenses serve me well. Even if I'm a few generations behind, I don't think I'll be replacing them.

In your specific uses and your specific style of operating your gear. Your singular experience is irrelevant for sweeping generalisations

I delineated my specific experience, which can differ from yours (have you used the 85 1.2 II for more than a few months, which this thread is originally about?). It's also probably pretty accurate of what to expect with similar combinations of equipment, barring copy variation.

If Canon releases a III model they could jack up the price, like what they did with the V2 model of the 35/1.4.

The only time I can see it being worth upgrading to a newer model is if it's significantly better in some way or introduces new tech. I have the Sigma 85mm f1.4 and I'm beyond happy with it, I don't see myself 'upgrading' to a newer version.

Or if something goes wrong with your current lens... it takes a dive into the ocean or does a somersault onto the sidewalk.
