Well if they make it from carbon fiber like Arri Red and Kinefinity have done with their bodies, I would certainly welcome it. But that would cost more than magnesium alloy and let’s face it… there is zero chance the R5C will have a carbon fiber body. As for RF lens strength… I’ve seen more than a few videos like the one below. Why are the Canon CN-E lenses metal? Could it be to make them tougher so they can stand up to rental house use?
I’m not saying plastic is bad. But if you want gear that can take a beating, then plastic is not ideal. Does this really need to be explained in 2022?
