Another announcement cycle is out of the way, so what’s next from Canon for the EOS R system?
- Thread starter Canon Rumors Guy
- Start date
My personal understanding of "halo" is narrower than @SwissFrank's - I wouldn't include a lens like the MP-E, because it offers something valuable and unique for specialists, albeit within a minor niche, and there's no easy way of achieving the same results with other gear (plus it's not that expensive). I would include the RF 1200 though - because its practical benefit is so small, and the alternatives are more appealing/cheaper for many potential customers, but it means they can claim the system offers native glass to that extreme focal length. I wouldn't be surprised to see maybe one more, perhaps a f/0.95 prime or a reborn 200mm f/1.8, but that's about it.

It's definitely special. I'd lump it with the MP-E - a unique product that offers a way to do something that can't easily/practically be done another way, that is of great interest to a small number of potential users. I'd treat that differently to the essentially pure bragging rights "we have the widest aperture 50mm", where the difference is much more subtle, and the cost differentiator from its nearest equivalents much greater. But I'm probably splitting hairs over semantics at this point

I think it is 16 mm
Canon Patent Application: Canon RF Primes
One thing that is notably missing is the filling out of the primes for the RF mount. Not just the dizzyingly fast halo primes, but the ones for normal people. This patent application discusses aberration correction when its close focus and has the embodiments of a lot of lenses that I know...

While I very much agree with that, Canon is also missing some RF staple lenses.
I was kind of expecting the 135 to be f/1.4 for that reason.
Although, I do have to admit f/1.8 with IS was a better choice.
Canon does have so many patents for statement lenses to draw from.

No, you're looking at the wrong 24/1.8 patent. Here is the optical diagram for the 24/1.8 in the patent you linked:I think it is 16 mm

The design that actually became the existing RF 24/1.8 is one that CR erroneously claimed was an APS-C lens patent. Here is the diagram of the 24/1.8 (actually 24.72mm f/1.85, with an 11.0 mm backfocus distance) from that patent, and below that is the block diagram of the existing RF 24/1.8 lens:
So I restate: the existing RF 24/1.8 has an 11 mm backfocus, so there's no reason the optics of the EF-M 11-22 with an 11 mm backfocus couldn't be packaged in a barrel with an RF mount for APS-C R bodies.

Well, audio improvement is an opportunity being overlooked imo if targeting video market, after putting all the R&D and speed improvements, oversampling, racing to crazy insane 8k, it seems obvious. But not something clunky like the huge honking XLR preamp box for the Sony FX-3 and FX-30. The tech is there, smartphone recordings for audio are pretty decent, even without a lavalier.

Nice explanation, so optic design transfers easily and a housing mechanical redesign- I remain baffled that these lenses were not made a year ago BEFORE the R10 and R7 came out. Same with other M optics. Probably lots of back and forth with marketing, engineering and management as to future planning and watching market changes.
