It took Canon six years after the release of the 300D to release the EF-S 15-85mm. If they follow the same interval you might expect the wide standard zoom lens you want from Canon in 2028. I don't think they will ever release a lens like this in the RF-S mount. It would be too detrimental to the sales of FF lenses.

I'm sure it's the other way around. A Canon APS-C crop f/2.8 is equivalent to a full-frame f/4.5 when you compare image noise and depth of field at the same shutter speed, angle of view and distance etc. That Ef-S 17-55mm (28-90mm f/4.5 FFE, the size of the original EF 24-105mm f/4 L lens and 25g lighter) cost more in purchasing power when it came out than any of Canon's 24-105mm f/4 L lenses when they came out, and I know which I would rather have.

I have the EF-S 17-55mm and the EF-S 15-85mm. I bought the 17-55mm not long after it launched and it was pricey at the time selling for around $1,200. I don't think we will ever see a high end crop lens again from Canon. The only hope to see this kind of lens is if third party RF lenses will appear some day.

Those will happen eventually, but not until the third parties can be sure there aren't any unannounced features of RF mount and their patent lawyers are satisfied that they have avoided Canon's patents. Remember that Sigma were warning people not to use the in camera vignetting corrections with their Art lenses even 25 years after the introduction of the EF mount (they've cracked it now).

Yes, it’s too bad for those who want such zooms. I shot exclusively with crop cameras for 16 years, and never wanted such a lens. I prefer either the longer range zooms, like the excellent 18-135 options on EF-S or the even better 18-150 on EF-M and RF-S, or fast primes, which are plentiful and getting more plentiful. For me, the 17-55 F2.8 was neither long enough nor fast enough. But that’s me. If you absolutely must have a fastish short range zoom for your crop camera, you might be out of luck with Canon. It’s unlikely that complaining about it on this forum will change anything, but maybe it makes people feel better. If I were on the Sony or Nikon or Fuji forums, I might just complain endlessly about the unavailability of anything like the Canon RF 100-400 or 85 F2 (or 600 F11 or 800 F11, or 16 F2.8, or…). Or I might just switch to Canon to get those lenses.

If you judge the EF-S 17-55mm lens today then you are doing it an injustice. At the time of its launch in 2006 it rivaled L lenses. It had fast AF and great IS along with very good IQ. I used the heck out of this lens for many years and it delivered very good photos for its time. I doubt Canon will ever make an RF-S lens like the 17-55mm or 15-85mm in the R system. Canon needs to give the RF-S mount a lens like the 24-240mm

That lens is equivalent to 40-400mm on full-frame, pretty much an all-in-one telezoom. A super wideangle zoom is more pressing.
