CanonWatch spotted the patents for the new 100mm f/1.4, 135mm f/1.8 and 500mm f/4L IS RF lenses. I am pretty sure both of these lenses will be released within 1-2 years!
CanonWatch and CR also report that Canon will announce three new RF lenses in early 2020:
RF 24mm f/1.4L
RF 135 f/1.8L
RF macro
Nice!
