Canon Patent Application: Fast APS-C Primes

[Canon Rumors Guy]

In this patent application (2023-130885), Canon lists quite a few primes with a significant ingress, but also more notably a smaller image circle than what would normally be used for APS-C. For Canon APS-C, that’s 13.66mm, whereas all these lenses have 12.50mm. Super-35 just in case anyone is thinking that is around 14.2mm so they

Now hoping no screw-type STM, and actually uses linear motor like STM(the one 3rd parties love to use).

Bring them out, shut the haters up. Canon STONKS.

Canon seems to be trolling me for sure .. Here Richard.. another image stretcher for you.

Looks like 22mm f/2's back on the menu boys!

Would be nice if they add a 11 or 9mm, too

Maybe a 10-20 or 9-18 f2.8 zoom will work better

The patents include both 9mm F2 and 11mm F2, though they may not actually be produced.

I don't think that canon will produce any f/2.8 APS-C zoom any more.
I hope I am wrong.
OTOH, f/2 prime is much smaller and delivers much more light on the sensor.
And sometimes that is really needed.

I did read the patent description!
I did realize that those are included!
And because of this, I wrote my comment.

The EF-M 22/2 is highly considered. So getting an RF-S version is almost a no-brainer to me.
And this is representing the typical FF equivalent of a 35mm lens.
But for people loving primes, something wider would be cool to add as a really nice prime setup.

Or what do you think?

The lack of such lenses is one reason I would still steer at least some people to the M50 rather than the R50/R100. The latter really need such lenses if they're going to be a complete replacement for the M50.

I gave up hoping for decent APS-C zooms. Probably will buy an R8 instead. Canon won i guess.

Seems they know their business. Shocking.

On a serious note, the R8 is quite nice. It's the same price as the R7, and although the controls are not as good (the lens control ring or using Fv mode mitigates a lot of that), the R8 performance is overall better (battery life notwithstanding).

I would have preferred something in the size of the R50, or even R50 without a viewfinder.

The R7 has nearly twice the resolution, and in my world that's no contest for the R8 vs R7 as well as the low fps in EFCS. YM clearly V from mine.

Seems like Canon paid attention (retrospectively!) to the devastating recent critique in DPR of the R50, where the main criticism of the R50 BODY was that ... they're weren't many APS-C lenses to fit it ...

That 9 would up my astro game. I get by with the Tokina, but a fast ultrawide prime would be a forgiveness rather than permission purchase.

Don't get our hopes up...I doubt Canon pulling a Thanos, where Canon is making all the decent price&spec primes.

I feel quite sure that an RF-S 22/2 will come. It would be nice from Canon to add another one.
But I won't say anything about my expectation on price

I'm worried those EF-M lens might have flange distance that's too short, turning it into RF might end up a 24mm/f2. EF-M15-45 turned into RF-S18-45.

These patents are new designs. Maybe based on the EF-M, but new optical formulae. That means they are calculated for the RF system and its flange distance.
So IMO you'll only have to worry IF and WHICH of these lenses will become a real product.
But the patent is as it is and it shows a 22/2 formula.

I don't know, if the flange distance was the reason that EF-M15-45 turned into RF-S18-45.
Maybe there were other reasons that made Canon decide to make it start at 18mm.
