Correct. An RF 40/2.8 could be made, of course, but it wouldn't be flat like a pancake.

What are the lenses you wish cabin would make?

Yes I have read that a few times over the years here. With that being the case it's just a pipe dream. Any 40mm of consequence with the RF flange/mount could only be as small as the 35 STM most likely.

A fast 28mm is all that’s left on my wishlist, f/2 or wider, it doesn’t even need a red ring.
I’m currently considering repurchasing the Sigma 28mm f/1.4 Art, it’s been almost two years since I got rid of mine, and there’s no alternative in sight. I no longer have any EF lens, but I still have the adapter, so I’m considering making an exception for this one, and keeping it as long as necessary.
I could also enjoy having a 20mm f/2.8 or f/2, at least something mid-range to graduate from the RF 16mm f/2.8, but that is not as important to me.
The system has options for everything else I could need.

If Cabin doesn't want to be doomed they'll have to make a superzoom of f0.85, at least otherwise Sigmaron will sell they third party Tony lensesf/1,2 perhaps?

All three or maybe you need new glasses - read the name of this thread.Sorry, but am I perhaps getting demented, senile or alzheimerised?
Who or what the f**k is "Cabin"?

Cabin is a new Chinese lens manufacturer that has been granted an exclusive license by Canon to create FF AF RF lenses. They will start releasing the Halo lenses that everybody is clamoring for: the RF60-600mm f1.2 that you suggested, the TS 14mm AF, RF 35mm f1.2, RF 24-70mm f2 etc.Sorry, but am I perhaps getting demented, senile or alzheimerised?

This will free capacity at Canon, so Canon can focus on the really important lenses like the RF 200mm f2.8 L macro lens, the RF 300mm f4 L macro lens and the RF 600mm f4 L lens with built in 1.4 extender.

I kinda left this thread, but I found EXACTLY what I'm looking for, and it should explain it better without us talking in circles.
This madman disassembled a Meike 0.71X speedbooster and stuck it in his RF 800mm F11! And it works!

That. That's it! That is precisely what I want from Canon, exactly that; a 570mm f8. And if this guy can literally glue it onto an 800mm F11, surely Canon can glue their own 0.71X speedbooster in the same spot and sell it without any extra engineering? Like the YouTuber suggests.
It would go *great* with that 39MP R7II.

What you are looking for was entirely clear. The only 'talking in circles' is that you seem to believe that what you are looking for makes sense. Consider that you called the guy who made one a madman. Canon's engineers are not.
The YouTuber took a lens with 5 elements and merged it with a lens with 11 elements – 16 total. A properly designed 600/8 would have fewer elements, be shorter in length, be lighter, cost less to produce (= more profit for Canon)…and it would still work with a FF sensor. Sorry, I don’t understand why you believe the idea of a speedboosted 800/11 makes sense.

Buying the RF 600mm f11 (or the RF 100-500m or RF200-800mm, or EF100-400mm II + 1.4 extender, if you are willing and able to spend the extra $ or €) would make a lot more sense than this contraption. Both f8 and f11 are not very suitable for dawn patrols or low light bird photography, so the one stop “gain” by adapting the RF800mm will not make much difference. And I strongly suspect that the image quality of the combination of speedbooster and 800mm f11 will fall apart on the (rumored) 39mp sensor.I kinda left this thread, but I found EXACTLY what I'm looking for, and it should explain it better without us talking in circles.

There is no one-stop "gain" using a 0.71x speedbooster. There is no change in the number of photons per duck as the increase in light intensity on the image of the duck by reducing the f-number is exactly offset by the reduction in the area of the image of the duck because of the reduction of the focal length of the lens. It's not the iso but it is the number of photons per duck that determines the S/N in the image of the duck, and this depends on the area of the front element (entrance pupil) of the lens, and TCs and speedboosters don't alter that.

Not really, not on that tier. It's not that much of a difference going from f/2 on the 28-70 to f/1.7 on the Leica.
I'd rather buy a budget 28mm f/2 to f/1.8 for personal use, or a 28mm f/1.4 L for work, than spending more than I did on my main camera and main lens together (R6 + 28-70mm f/2) for a secondary device.
Whatever 28mm I buy, it can't be more expensive than my main gear. Don't get me wrong, I very much like the Leica, I've tried the camera and I'd love to own it, but it's not the tool I need.
For now, I have the RF 28 pancake for personal stuff, the 28-70mm f/2 for work, and I recently added the RF 45mm f/1.2.
I need at least one fast prime between 28 and 50mm, preferably on the wide end, with an aperture wide enough to be worth putting down the 28-70mm f/2, when the light is not enough and flash is not a possibility.

It always bugged me that Canon (and other makes) have 100 variants of the 70-200, but no 70mm prime. would love an internally focusing compact 70mm f/2.8 prime.
Fuji offer a 50mm f/2 prime, which is very compact for what it is. very premium, internally focusing, beautiful and polished aesthetics -- all metal. I wish Canon made something like that.
would also be nice to see a macro lens with lights, such as the ef-s 35 2.8 which i've owned a while now. i adapt it to my Canons and Fujis with beautiful results. i'd like to see a bit of a longer one, maybe a 100 f/2.8 IS macro (non-L) to keep the costs down. wouldn't even mind a 100mm f/4 macro as i tend to stop down anyway.
