Canon's pricing is pretty extreme, I'm sure they're great lenses but at this price I think we've gone into crazy land. I would still keep an eye on them in case they ever do a decent entry FF body, adapting though. Way way too costly for native lens purchases. None of the MILC lens prices are good, but perhaps Sony/Nikon are not as bad. I won't write Canon off, unless they come out with another crippled RP type camera
Jury still out on Nikon, maybe they will sell a ton of these retro cameras. They don't have much happening with APS-C lenses on Z mount, and what they do have is slow F6.3 stuff. Right now MILC is fairly easy to ignore from a photography perspective!
