A reminder of what the Mitakon 135mm F/1.4 looked like. $3,000, I'm sure Canon would have its eye on a similar cost.
I'd be interested to know if the Canon RF 135mm F/1.4 would accept extenders. 189mm f/2 and 270mm f/2.8 would almost allow the lens to serve double duty as a 200mm F/2 and 300mm f/2.8, which would make a high pricetag a little easier to swallow.
