The Z lenses seem to be very important to Canon if they're filling out the trinity line-up that quickly. I hope Canon will complete the F2 trinity (if there was/ is one planed) and a small and compact 24-70mm F4 L would also be very welcomed to fill out the F4 trinity. As I've read/ heard, the RF 24-105mm F4 L isn't really considered being part of a F4 trinity. I not quite sure about that though. On the one hand, for the Z trinity 24-105mm F2.8 seems to have set a new standard and maybe Canon does consider the F4 version of the 24-105mm as part of a F4 trinity. On the other hand, there used to be a EF 24-70mm F4 L in the F4 trinity for EF mount and the 24-105mm is not on par with the 70-200mm and 14-35mm imo. And while we´re at it, a F2.8 non L 70-170mm should be a given I guess.
Wow, that´d be a lot of trinities (or trinitys? the dictionary said there is no plural form)
Z-trinity:
RF 14-28mm F2.8 Z (rumored)
RF 24-105mm F2.8 Z
RF 70-200mm F2.8 Z
F2.8 - L-trinity:
RF 15-35mm F2.8
RF 24-70mm F2.8
RF 70-200mm F2.8
F4 - L-trinity:
RF 14-35mm F4
RF 24-105mm F4 --> does it really count?
RF 24-70mm F4 --> not available...are there any rumors???
RF 70-200mm F4
F2.8 - non L-trinity:
RF 16-28mm F2.8
RF 28-70mm F2.8
RF 70-170mm F2.8 ??? --> rumored lens
F2 L trinity --> hopefully there will be lenses to complete it
RF 28-70mm F2
rumored:
RF 24-70mm F2
RF 70-135/ 150mm F2
RF UWA F2 zoom --> I am guessing it will either end at 28mm or 24mm depending on what Canon does with the successor of the RF 28-70mm F2. I have no idea where it would start.
Five trinities (plus maybe the extra RF 24-105mm F4) would give us 15-16 great options and we're not even counting the 15-30mm and 24-105mm non L
good times to be a photographer (if it weren't for all those video-centered lenses)
