Sooooo, f/11 you say? What’s Canon up to with these upcoming supertelephoto lenses?

Kit.

Non-zooms, with this focal range... unless these lenses are decent macro lenses, expect people to use them mostly with cropping.

Which will further reduce their effective aperture.

... But from the stand point of a photog that understands light and the requirements needed to make a shot, I feel like this offering will fall short. ...
Most of my bird photos are f/9 or f/10 and ISO up to 6400 and I can AF comfortably with R camera at f/11. I don't see f/11 on R that restrictive to take pictures as light and requirements are concerned. I think diffraction may be more restrictive. If f/11 is a good compromise for weight, agility and cost, then so be it.

I am very interested in learning about the other three lenses that are due for release in 2021. WIth the TCs being released this year I am hoping for one larger aperture super telephoto in 2021. Ideally I would like it to be a 500 mm f4 DO lens. If so it would be the only super telephoto I would purchase for the R system.

Sunny-16 rule: Bright sunlight means shutter speed equals the inverse of the ISO setting for f/16

for f/11 you gain a stop in shutter speed. For ISO-100, the shutter speed is now 1/200 sec. For ISO-400, the shutter speed becomes 1/800 sec. Most newer sensors are excellent at ISO-400.

This makes hand holding these f/11 lenses feasible.

The advantage that a mirrorless has over the DSLR is the viewfinder brightness when using lenses of apertures of f8-f11. The DSLR will be dim making it more difficult to manually focus or track a subject, while the mirrorless EVF will have the brightness level of a fast lens. I put my 100-400 plus a 2x extender on my M5 and was able to manually focus quickly on birds at my pond. So, an f11 super telephoto will be just as usable as a faster lens but the only drawback is the higher ISO required. There are a few great noise reduction software packages out there that can make moderate high ISO noise a mute subject.

These f/11 lenses aren't for me, not in Scotland when most of my photography is on rather gloomy days. But on a bright day someplace bright I could see a 800mm f/11 lens being great value or for someone just getting into it. Wildlife photography has been one of the most expensive routes into photography(Compared to people or macro where you can get 1-2 sub £500 lenses and you are good to go).
Not if you buy RF lenses

Cost is irrelevant if you can't get the shots you want. ;-)

I'm not arguing the cost/weight savings, hence me saying I'm not the targeted audience. I am curious how many people out there have a desire for this type of lens though, in comparison to those wanting something faster, even if more expensive.
And the shots you want are irrelevant if you can't afford the gear needed to get them. ;-)

I'm not in the target audient either, but Canon usually does its homework. If I was a person that had a 70-300 consumer zoom (that usually don't take TCs), I'd look into the 600 f/11 if it was under 1500. It would be even more interesting if it telescoped to the in-use length. At f/11, the lens diameter could be similar to a mid-range/short tele zoom, and if it collapses when stored, then it won't necessarily have to be that much longer.

Great! It could be inexpensive and not too heavy. Both could bring me into wildlife. The results would be quite simillar to M43 f/5.6 lenses which do pretty good job

Aside from light, are people forgetting about the focal length here? You're going to need some pretty fast shutter speeds at those lengths. Other than the mid afternoon on 100% sunny days you're not going to get it

Have you ever used these focal lengths? I have regularly - 400mm DO II + 2xTC at 800mm and 500mm + 1.4xTC at 700mm - down to 1/80s on occasion.

Can someone translate the patent numbers? Is the length of the lens provided?
The 600mm is 310 mm long and the 800mm is 370 mm long according to the patent linked in the other thread. That is, with the flange distance subtracted, so that these lengths refer only to the part sticking out past the mount.

They also appear to have only 9 elements, the majority of which is rather small. So these lenses should be fairly compact and light for the reach they provide. Given that they appear to be STM lenses, I am also expecting them to be shockingly affordable.

These may have been in preparation for taking pictures at the Japan Olympics from the stands and not for wildlife. The reason to buy one of these cameras may be perhaps- is to have something my cell phone camera cannot do.

I don't think most people think astrophotography when they hear f/11, but the moon is bright AF. So if you're a lunar photography specialist... Might actually work for planetary photography too, although I can't translate 600mm/800mm to the equivalent telescope configuration in my head.

But as others mentioned, airshows and yachting and the like were the first thing that came to mind.

Definitely made with casual photographers/masses in mind. Not everyone wants to shell out the money or deal with the weight of a fast telephoto. Also not everyone makes the effort to chase good light; they just want that snap shot of the bird/animal/wildlife when they're out and about during the day.

"Who are these lenses for?"
Somebody who has been wanting a 600mm lens they can put in their pocket.
It seems there is always someone.....
