Lenses 35/21 Gears 46/20
They surely did roll out those MKII L series one after another. Never tried any but I believe you. I honestly thought the MKI 17-35L was a damn good lens for its time as well as the 28-80L I never owned the 28 or 24-70.
What about the tiny 24STM?
I have 16-35 L 2.8 II and it is just another lens which leaves no practical reasons to buy RF lenses in 16-28 focal lengths. Even small size doesn't count for optical quality and large aperture, plus fast, quiet and accurate AF.

24STM is high quality glass and fast AF.
