A History Lesson on Canon 20mm Lenses

...Canon was proud of their floating rear focusing system with the claim that you'd get sharp images no matter the distance of the subject. I guess this could be considered true if every image is soft. ...
Thank you very much for that phrase. That made my day and I still have to to gasp for breath laughing that much :ROFLMAO:

I bought the sister lens of the FD 20, the FD-n 17mm f/4 maybe 40 years ago 2nd hand for 450 "Deutsche Mark" / 200$ of mid 1980s.
While it has the soft corners too it was good on film (ISO400 B/W) and rendering was o.k.
In terms of flares it is great because it has lots of them and it is good enough for 2k or just 4k video. If I will ever do some night scene of a car with strong headlights, this might be a good choice because of these flares!
