Canon rumours says these lenses are coming this year. I can’t help but think how incredibly small these will be if they come indeed. In case of 600 DO the background blurring will be like a 70-300mm F5.6 lens at the long end, none of the 70-300/5.6 are sharp enough. 800 DO seems better because of still respectable aperture but that long FL !! What seems to be their application, the thinking behind them? Exciting, and i hope they are priced nicely. I wish the 600 DO was F8 instead of F11.
600DO is comparable to Sony RX10 IV lens which has effective specs of 600/10.8. And its a zoom. That may give us a hint how incredibly small these lenses will be.
Length of the 800/11 is 389mm which would be to the sensor plane so the physical lens a little shorter but not that much shorter considering these are mirrorless with the sensor much closer to the mount. The diagram shows a very simple lens design.
Also of note from the Nokishita is these aren't L lenses and have STM, not USM. So they are going to be cheaper lenses as they well should be given the specs.
Use cases?? Wildlife video maybe. Cheap birding lens??
Biggest question is if we look at the entire rumored list of lenses for 2020 there seems no reason to be releasing TCs but we know they are. TC doesn't fit the 70-200/2.8 so would only be useful maybe on the 70-200/4 (remains to be seen if it is compatible) and the 100-500...although the 2xTC seems to be pushing things up to f/14 on that lens. TCs on these f/11 supertele lenses seem to be a fool's game but I may just be that fool to try
While the 600/F11 and 800/F11 will likely be competitive low-end (non-L) lenses, the great thing about this is that Canon seems to still be actively working on DO lenses, so I'm still hoping for a 600/F4 or 800/F5.6 DO L prime lens at some point in the not too distant future.

Yes for sure...600/4 DO for me please, pretty please...
Really disappointed in the list of new lenses for this year. I guess there is more money in lower priced higher volume lenses. Still waiting for a 150-600 f5.6L like the FD lens. Never produced a EF version and it looks like there is not going to be an RF version either.

Oh, man. I predict some very angry Canon users when they see f11. If f7.1 wasn't bad enough...
Good news? Canon must be confident about their AF ability at f11. And when using the lens, you only have to think about a couple of aperture values and not boggle the mind with thinking about going out to f4 or f2.8. (that's a joke). One can also hope that Canon has some sort of magic sensor tech in tap that defies the laws of physics and gains 4 stops in noise control. Well, there could be some truth to that last one if the lens and IBIS systems allow for insanely low shutter speeds. For static subjects that does effectively improve the noise control more. If the new lenses offer 3 stops of IS over EF lenses, then were looking at something closer to f4, eh?
I think I see why Canon decided on making the slow, tiny telephoto primes and not faster ones. The EF versions are still pretty fresh and could use a bit more time making sales and they don't change the overall size of the system much by adding the converter.
My take is that the big question is image quality. The patented formula has the DO element first, like the old DO lenses with low contrast. That doesn't bode very well. On the cool side, they will probably have a slick collapsible design and be very lightweight.

I don't think the order matters*. According to Canon, the third gen DO was designed with a "gapless" DO element, which reduced the flaring and other aberrations.

Good idea: collapsible would be good - and given the simplicity of optics should be easy - and a long hood covering it and then extending all would mean the placement of the DO element would be well inside the final unfurled "structure".
I wonder if this rollout is the first stage of learning how to manufacture these (small) DO elements reliably and gain experience to make the larger ones for the f/4 and f/5.6 long guns. It's the Canon way
F11, my oh my. Instead of going forwards they're going backwards IMHO. I shoot a lot of (extremely) low light and fast lenses are key in what i do. I do like the potential of the RF mount (have the EOS-R) and was looking forward to play with the R5 soon, just have zero appetite for any slow Tele. I'd rather see a 600 2.8 than a F11. I'm interested to find out how the R5 adapted to a 600 F4 compares to a A9 with native 600.
All this f/11 hand-wringing. Canon may signaling with f/7.1 100-500 and now f/11 tele primes that the R5/R6 high ISO is going to be much improved. It has been suggested they may use the dual gain sensor technology from the C300 III.
The original definition of the "telephoto" was a lens that needed less extension than its FL. Think about trying to use 300mm or more lenses on a view camera having roughly 300mm/1 ft. of bellows. But to start, the 600mm is about 2 ft long. If they can get it less than that: great.
I have an old vivitar 600/8 T-mount. It's not particularly heavy, it may just be an achromatic doublet on a tube, like some of the old Leica teles, but it's definitely not compact. I need to measure and see if it's 2 ft or not. 600mm lenses are big in general, if this one isn't, great.
F/11 is slow but high iso is much better than it used to be. 54.5mm diameter front element can get you a 600mm f/11. So I expect a long, skinny tube, I guess. I hope it doesn't need to be stopped down.
Well, there could be some truth to that last one if the lens and IBIS systems allow for insanely low shutter speeds. For static subjects that does effectively improve the noise control more. If the new lenses offer 3 stops of IS over EF lenses, then were looking at something closer to f4, eh?
