CanonNews discovered another patent detailing some interesting kit zooms that start off at the ultra wide-angle. It's unknown if Canon would ever make such a lens, but the zoom range is very intriguing.
It's also a lens that could double for a standard lens for APS-C. However, it would bigger than it would need to be since it's designed to cover the full frame image circle.
This is the second patent found with these lenses, indicating to me at least, that there is active interest inside of Canon for this type of lens.

Like how they did full frame kit lenses back in the 35mm days, but with the benefit of modern technology.
Perhaps a 7D-class camera is expected? I don't quite think they're ready to kill of EF-M yet though.
yeah, on a full frame camera, those lenses even though they are consumer, they are very much "shut up and take my money" lenses for me.
Autocorrect or Freudian slip?
I would prefer the 17-70 because I like the 70-200+x range much more. A 17-70 would be a convenient lens for all those situations where I need "wide" or ultrawide. Only one caveat: I would like a 17-70 5.6-3.5 lens because narrow aperture is o.k. for 17mm but wider aperture very welcome for longer focal lengths.
In the next days I will test FD 17mm with the RP for IQ if ... my RP will be delivered after some odyssey through Germany.
This. 18-80 / whatever on a RP II (future state) for travel.
The image height of 21.64mm seems to indicate FF lenses. Double checked with an AOV calculator, and 17mm on FF gives 104deg, so the half angle of view (51.19deg) fits as well.
I know that, but the focal length range suggests an APS-C “normal” zoom lens. That is, the FF equivalent of something in the neighborhood of a 24-105 or 28-135 type of lens. Would be a rather interesting zoom range on FF, Ultra-wide to short tele though.
