I think people are vastly underestimating these STM DO lenses. Notice they're not even L series--they're basic STM.
My feeling about this is that these lenses are going to be far cheaper and far better in size than y'all anticipate. I wouldn't be surprised if they top out at $1000-1500 at most. That's a *huge* market that Canon can tap into versus a $12,000 lens, and I could even honestly see myself grabbing a cheap 800 f/11 to throw in a bag and forget about.
It's becoming more and more apparent that Canon is throwing away the lens design handbook of 40 years ago and is making whatever lens they want to make. For the new focus system, F/11 is basically the new F/5.6, and Canon would be stupid not to leverage creating a new cheap market of the longest, cheapest lenses. Think of how many people are perfectly content shooting F/5.6 or F/8 on a crop camera, which is almost definitely going to have more noise than this.
On a totally different note, I think that 85mm f/2 is in my future. Would be great having a 35 f1.8 and 85 f2 with the EOS R5 in a tiny shoulder bag when I'm not going somewhere just for photography.
