I’m with you on this.
Canon released a full set of CN-R full frame Cinema prime lenses in early 2024, priced around $4200 ish each. It seems to me that you’d be right about a 42mm F/1.2 being more likely a cinema prime lenses, than a non-L RF lens. Just my guess.
Canon would likely measure the F/stop in cinema T stops, placing it in the lineup between 35 and 50 as a 42mm T/1.3 lens, matching the other T/1.3 primes. (or 40mm T/1.3?)
40mm is common for cine prime lens makers: Zeiss Supreme Prime 40mm T/1.5, Cooke S7 40mm T/2.0, Schneider, etc… Canon would be competing in this space.
