Canon News has uncovered a patent showing optical formulas for fast RF zoom lenses, likely of the L variety. The purpose of the patent is to showcase a high-performance zoom lens design.
Of the three embodiments in this patent, only the RF 35-135mm f/2.8 seems like a design that has a slight chance of becoming a consumer product.

Are you a tech head or a photographer is more to the point, tech heads will always be seduced by the newest shiniest toy, photographers will take pictures with whatever they can afford (or borrow).
Come on, Canon, make it happen!
I like R5, but I also like 28mm lenses... and don’t have money for R5 (yet?). I actually almost sold everything, and now I stuck between options. Sony has nice 28mm and compact 35 1.4 is coming... but 35-135 2.8 is my dream zoom.
Anyway, I need more money, so I have time to see what’s coming.
I'd suggest a quick visit to Dr. Canon, only he can help in desperate cases like yours. ;)
It could be even harder for such an "extreme" zoom lens.
I know zooms are very useful, using them often. But, does it really make sense to buy a 90 MP Rs, without using the sharpest possible lenses?:unsure:
Where do you get your data? Bryan Carnathan for one competent reviewer would disagree. I would as well. My EF L lenses were very good but the RF lenses are definitely better. The RF24-105/4 is remarkably better than any previous EF version, just as one example. The redesigned mount is part of that difference. The R5 demands extremely good glass & the RF series works extremely well with it. If your concern is money why don't you write them off your taxes as a business expense as many of us do? The cheaper is better arguments are irrelevant. We are talking about various lens characteristics that lend themselves to better files.
