Canon Watch has added two new lenses to the RF mount roadmap for 2021, claiming some one of a kind telephoto and super-telephoto lenses are coming for the RF Mount.
First up, an RF 250mm f/2L IS USM. This sounds good on paper, but I don't think 250mm is a focal length consumers would understand, especially those that are currently using the EF 200mm f/2L IS USM, which is my favorite Canon lens by the way.
Second up, an RF 500mm f/2.8L IS USM. I'm no engineer, but this would be a massive lens. We have not yet seen an optical formula patent for this yet.
The third is the long-rumored RF 70-135mm f/2L USM. I have been writing about this lens for a while now and it continues to get mentions.
Take this info for what it's worth, but I guess anything is possible.
But, what a statement lens. Love all three of these rumored lenses.
I tremble just imaging what it would cost.
I heard it comes with a gym membership to help those who might not be able to shoot it handheld.
Thank you Canon!
Just need to keep working out to carry this lens and gotta keep working another two years to afford it!

For the 500mm f/2.8 there is already such monster by Sigma. This should give an idea of the size of such monster:
But seriously, I'm all for weird designs.

Not addressed to me, but I own it. Fantastic for most sports in less than ideal light, and also very nice for portraits.
And yes, I want all three of those lenses. But, probably would focus on the 70-135mm f/2.
A really, really great night sports/news combination would be RF 28-70 F/2, RF 70-135 F/2, and RF 250 F/2.
As for the 500mm f/2.8, now that's fascinating. If Canon can apply the same design principles of the EF 400mm F/2.8L IS III and the new 600mm, this might not be all that heavy of a lens. Maybe with the new lens designs they could pull off a 500mm f/2.8L IS that's only as heavy as the old 600mm F/4L IS? Add in DO or other designs and maybe it could be very manageable. This would be a dream lens for football, I know a lot of photogs who shoot with the 500 F/4 or 600 F/4 and sacrifice aperture for reach.
But the prices are going to be eye watering and they are going to have to use DO elements to keep the size and weight down to manageable levels. I used to shoot tennis and it wasn’t unusual to see ten Canon 200f1.8 and f2’s in the photo pit, but I’d think 250mm might be a bit too long for them. Wide field Astro was another big market for the various super fast 200’s, indeed the very rare reverse engineered FDn 200 f1.8 version collect huge money because they don’t need power for the focus by wire af motor, though many of them have issues with cloudy elements due to age nowadays.
Of course this brings us neatly to the legendary and very rarely seen Canon 300mm f1.8. https://petapixel.com/2017/04/27/canon-300mm-f1-8-yes-monster-lens-exists/
Scale that lens up 10-15% and you’d have your 500mm f2.8 DO.
