You're not the target customer for the super teles so you do not understand the design history of the long white primes.
As such further discussion is moot.
As such further discussion is moot.
But you are referring (at this moment) to super-tele in the EF line, and not the non-existent RF line. As far as RF super-tele, you have absolutely no idea yet what they will weigh.
Then I kindly turn you towards a look at the other RF lenses that are already here. What is lighter than an EF 85mm f/1.2L, EF 50mm f/1.2L, EF 28-70mm f/2.8L? Any of the RF's? No. Sure, the RF 70-200 is lighter than the EF version. Isn't that just about it? The Canon EF 24-70 is 95gr lighter than the RF version. So where is this advantage of RF over EF? I don't see it when it comes to weight, which for some reason, people keep trying to claim.
You claim there is a weight advantage to RF. I don't see it.
