Phenomenon

When shooting in a high-temperature environment, the intended exposure may not occur, and the brightness of the captured image in the same scene may vary, or the error “Err01” may occur.

I had to go to the Canon once. Worse yet, it was in New Jersey. 😉

looks like only lenses manufactured in 2022 are affected, my 50 1.2 is at least a decade old. I would guess that most of the 50 1.2 ef lenses out in the wild are not going to be part of the recall

But it's an interesting data point that Canon did a production run of this EF lens last year.

Vast majority of pro shooters I know use EF mount cameras, not mirrorless.

I was trying to find the article I read, but can't. However, my understanding is that Canon keeps making lenses until they are officially discontinued.

They go to "Final Sale" status until supply runs out and then the status changes to "Discontinued".
However, you are correct in that internally "Final Sale" is discontinued.
