Bokeology by Deep Research - f <= 2.0, 28mm to 75mm

Had the deeper chatgpt evaluate bokehs of 28mm to 75mm Cron, Lux and Nox lenses. Nothing really new, I'd say. Do you agree with the AI's summary? In the current 50mm range, do you prefer the 1.4 (11728), the 0.95 or the 1.2 reissue bokeh -  or does this depend - and if so, on what, precisely?

Are you serious? What a load of rubbish. I spend a lot of money for what is in focus, not for what is not.

Focal length.

The „article“ pretends to talk about „fundamentals and definitions“ and ignores the simple fact that the depth of focus of a 28mm Summicron can‘t be compared to a 75mm Summicron when both lenses are used with the same opening. So it is only concerned about names, like Summicron, Summilux etc and not about what you see.

Looks a typical ChatGPT "article"...  trivial observations taken from a mix of sources with "intelligent" cross-checks, so leading to trivial conclusions and various inconsistencies (apart the one observed by Uli, take note of  <The classic Summicron-M 35 mm f/2 (1958) – a 7-element lens – earned the nickname “Bokeh King”> 😁 )
