Patent: Canon RF 50mm f/1.4 USM and other primes


Nov 2, 2016
Canon's rangefinder lenses from the 1950s and 60s were even much smaller, my vintage 50mm f/1.8 has about the size of two bottle caps stacked.
Yeah. I used a Nikon rangefinder in college, when I was on the newspaper. Pretty small too. So we’re my Leica lenses for my M5. Though the 90 f2.0 didn’t seem small.


Grab your camera, go out and shoot!

The Leica 2.0/90mm must have been close to the size and weight of my Canon Serenar 100mm f/2.0 Leica M39 mount (LTM) from the early 60s - for a rangefinder lens this one is quite massive. I still use it, even for street shooting with my vintage Canon 7 (if I have enough time to get it focused). Ilove the vintage character of the images shot with it, plus it is surprisingly sharp in the center @ f = 2.0. Sharp enough for fine film grain.


whereas Canon's vintage nifty fifty 1.8/50mm LTM is really tiny and light, I love to use it in the street, stopped down it is impressively sharp for such a vintage lens.
