Are new dream lenses coming for the RF mount? [CR1]

I think it would sell well. People love the Nikon. When shooting in low light there’s a fair difference between f5.6 and f7.1.

Barring magic or changes in the rules of physics, the front element would still be about 40 inches in diameter. That's what f/2 means.

I have the 14-35 f4, the 24-105 f4 and the 70-200 f4. The 24-105 sucks for aperture stars while the 14-35 and the 70-200 produce beautiful stars. My old EF 24-70 had beautiful aperture stars and I really miss them. As soon the RF 24-70 f4 comes out I will sell the 24-105....although I have nothing to complain about the sharpness.

I said it didn't need to be a pancake and besides, Craig asked for a list of impossible lenses that would never be build so bringing physics into the discussion is decidedly tacky .

If it unfolds like the James Webb telescope then the set up time and auto focus (before you can take an actual shot) might be a little long for most wildlife applications.

Well, at Canon's prices, I'm not really looking forward to any lens to be honest.
Never owned a Nikon, but gee that 500mm f5.6 is a bargain compared to Canon. Oh and Sony's 200-600mm would be even better. Never in my 30+ years of shooting Canon felt so much envy for the other brands. Didn't even notice them.

The Nikon 500 PF is more expensive than the RF 100-500mm, which as I wrote above, I find more useful and just about as sharp. The Sony 200-600mm is good value for money but it weighs 2.4kg, 0.8kg more, which is noticeable, and focusses down to only 2.4m, more than twice that of the RF 100-500mm. The grass may look greener but it isn't.

Yet in exchange for longer reach, slightly brighter on the long end, heavier, internal zoom and and less MFD you pay here in the UK; £1599 for the Sony compared to £2979 for the Canon so a difference of nearly £1400. For some the extra cost will be worth it and for others absolutely not.

A 500/4.5 DO with built-in teleconverter would probably get my money. I have and use most often the 100-500. The more I use it the more I love and respect it. But 4.5 would be useful at times. I also have the 500/4 L IS ii. It is an extremely sharp and crisp lens and only a wee bit over 7 pounds.
I was recently working a nest situation where I had to stay well back so put the 2x iii on the 500/4. Contrast was down slightly but sharpness was still extremely high, all that the R5 could handle. No fringing. I could make a print any size I wanted from those files.
So, here I have an amazingly good lens in my 500/4 ii. What would get me to replace it for a mere 8-10 grand? A 500/4.5 DO which is 2 to 2.5 pounds lighter and 4-6 inches shorter. Might not part with that 500/4. But throw in a 1.4 converter and have a lens 2 pounds lighter and 3-5 inches shorter, then Canon might very well take my money.
Also, putting an RF mount on the 32/1.4 would be a wonderful idea. My dogs got me and the M6 ii one for Christmas. What a great lens. And allowing Siggy to make the 16 and 56 1.4 lenses for RF would probably get me buying an R10.

With an R7 on the way (someday) I'd like to see an RF-S 15-50 F2.8 L IS. Just a little wider than the EF version with a bit of weather sealing, and some proof of commitment to the RF-S format from Canon by making an RF-S L lens. A few fast RF-S primes would be nice too.

14 years of EF-S with no L lens. Don’t hold your breath. APS-C is aimed at the consumer market. L-lenses aren’t.

RF-S 200-600 F4-5.6L IS or similar would be a dream for the R7... 
That combined with a price tag around 3k, dual USM motors and the minimum focus distance of 1m at 600mm - For Wildlife/Sport and Macro.
.. we can dream
And of course a RF-S super wide angle astro lens with low aperature.

But wouldn't that be fair? Lower aperature for same weight as the RF 100-500L - I'ld totally pay that
.Could be even a bit heavier, that's still fine (if it delivers in quality).
