ApoVision Posted May 21 Share #1 Ā Posted May 21 Advertisement (gone after registration) 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 -Ā or does this depend - and if so, on what, precisely?

UliWer Posted May 21 Share #3 Ā Posted May 21 39 minutes ago, ApoVision said: or does this depend - and if so, on what, precisely? Focal length. The āarticleā pretends to talk about āfundamentals and definitionsā and ignores the simple fact that the depth of focus of a 28mm Summicron canāt 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.Ā 2 Link to post Share on other sites More sharing options...
luigi bertolotti Posted May 22 Share #4 Ā Posted May 22 Looks a typical ChatGPT "article"...Ā Ā trivial observationsĀ 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 ofĀ <The classic Summicron-M 35 mm f/2 (1958) ā a 7-element lens ā earned the nickname āBokeh Kingā>Ā šĀ ) Link to post Share on other sites More sharing options...
PCPix Posted May 22 Share #5 Ā Posted May 22 Well - which is it then? Make your Artificial Unintelligent mind up⦠(canāt actually believe I spent the time skimming over this!) Example: The classic Summicron-M 35 mm f/2 (1958) ā a 7-element lens ā earned the nickname āBokeh KingāĀ or Summilux 35 mm v1 = āking of bokehā Link to post Share on other sites More sharing options...

For the most part itās an advanced parlor trick with a high level of self confidence. Itās scary how many people use it for advice or reference purposes.
