Oppinions to CANON high speed wideangle lenses

I had a 35/1.5. It was a bit of a dog wide open, and I traded it for a 35/1.4 RF Summilux. Which was worse wide open. But the Summilux was nicer, overall. I wouldn't get another of the Canon, and I do really like Canon RF lenses. My 85/1.5 Canon is much better, by the way.

The 35 RF Summilux was a dog, very soft at f/1.4 and vignetted badly!

I used to have Canon 1.8/35one back in the 1960's. It was better than the 35/1.8 Nikkor and probably as sharp as the 8 element first version 35/2 Summicron, with maybe a bit more contrast than the 'cron.

CANON 1:2.0 35mm (Apr.1962)
The "Summicron" is the Leica f/2-class lens in 35, 50 and 90mm with highest reputation for performance and all-purpose usage among Leica-owners. The name Summicron has some legendary sound. This lens by some photographers was sometimes called the "Japanese Summicron". For some reasons it could be seen as regression, because Canon already made a 1.8/35 in 1956 (which was together with the Nikkor the fastest at this time, and an excellent lens) and, 1958, an 8-elements 1.5/35 which again was the fastest wide-angle of that time. Oppinions about quality of the latter are divided, some say "speed" was seen more important as contrast and sharpness at design, like it was with the 0.95/50...

Anyway, in April 1962 the 2.0/35 came out and replaced both in production - with 7 elements/ 4 groups a derivation if the 1.8/35, but sharper and more contrasty in the center. And from the formula, very similar to the - later! - 7 elements Summicron design...

Furthermore black, small, and lightweight - just a handfull glass and alloy. Finally without "infinity lock". Looks like a Mini-SLR-lens, but disappears in a trouser pocket. The unimpressive outline doesn't hide the excellent working. Not cheap. Rare and sought-after. Whoever owns one don't give it away untill he gets something better. This is - 40 years after debut - available but costs much more.
