Just buy the RF 50mm F1.2. Stop complaining about the price, its cheap enough.Canon is the only remaining mainstream lens manufacturer without a reasonable 50mm lens that belongs to the 21st century, which is quite astonishingly ridiculous when you think about it (even Pentax has got one). All of their 50s bar the €2300 RF 1.2 are either yet another version of the decades old double gauss or barely evolved from it, with all that entails in regards to IQ (ie they're terrible by 2020 standards), and all of them with appalling AF.
Personally I'd like Canon to chase a level of ambition as high as Nikon tried (and not fully successfully so) to reach with the 50mm 1.8 Z, without IS (as IBIS is coming and I'd rather have Canon put it all in IQ), and without the Nikon's issues with onion rings / manufacturing problems, and I'd happily pay between €450 and €700 for it, but I'm rather expecting Canon to target a lower level of ambition with such specs unfortunately.
I would have thought such a reasonable, practical lens likely to end up in lots of hands and as a result quite a bit more likely to produce interesting pictures, a priority, at least more so than lenses designed to enable Canon's marketing department to trumpet the size of Canon's engineering appendage, but what do I know ?
