Autofocus was the major hindrance at the time so most lenses had a max aperture of f/5.6.
All FD lenses had a max aperture of f/5.6 or wider, with the exception of a few catadioptric lenses, and I doubt AF was a consideration here.

The 400mm DO II is the same width as the 300mm f/2.8 II and 16mm shorter. An f/2.8 400mm DO would have to be about 40% wider.The more I think about these lenses, the more I think about this lens:

I always wondered why it seemed like the 600mm F/4L IS DO was so close to a final design when announced by Canon, and then went *totally,* utterly silent. I wonder if they switched gears to develop that lens for the RF mount, and made the 600mm F/4L IS III as a stop-gap, final EF version?
If Canon is using DO on these lower end lenses already, I'm almost entirely sure that when a 600mm F/4L comes to the RF mount, it won't be much bigger than the original 600mm F/4L IS DO lens they had on display all those years ago. That size is just *amazing* for a 600mm lens, and it makes me wonder if they could do a DO 400mm f/2.8 even shorter than the mock-up 600 and about the size of a 300mm f/2.8.
Exciting stuff to see going forward.

Last year I was lucky enough to take a trip to the Galapagos Islands and I have to say I would have KILLED to have one of these lenses for that trip. Generally when our group would go out to see animals it was in the late morning and early afternoon and the sun was just insanely bright and you really can't be carrying a massive lens around since you're hiking all over the place and jumping on and off boats.
The fantastic range of 600mm or 800mm would let you get amazing shots of the animals and the sunlight there at the equator is so bright that f/11 would still easily let you get amazing shots at low ISO
Yeah... That’s exactly the first thing I thought. We’re planning to do that trip within the next five years, and I’m already trying to decide the gear I’ll be using. I’ve been eying the new RF 100-400mm L as a perfect pair for the 24-105 f/4, and I assumed that a specialized long white just wouldn’t be justifiable, either in size, or in cost. The 800mm f/11 could possibly be though, if it’s small and inexpensive enough.
I suspect there will be a lot of enthusiasts and travelers that will buy these lenses if it makes sense price-wise to jump into these lenses.
I wrote in an earlier post but will repeat it as it could be useful to you, the crucial telephoto lens for the Galapagos will be a 100-400mm or the new 100-500mm as most of what you shoot is incredibly close with the wildlife unafraid of humans. In our trip last year, I never needed 800mm , and my specialty is bird photography where in most places you need reach. And 100mm is too long for a lot of what you see.Yeah...

It was a 600mm F/4L IS DO lens Canon showed off in September of 2015. Five years ago already!What is that lens? You imply it is a mock up of a DO version of a 600 f/4? If so, why no green ring as opposed to an L red ring?
How many years ago was this thing displayed?
It is VERY interesting!
I was unaware of this. Very interesting! Canon may well have more surprises in store for us!It was a 600mm F/4L IS DO lens Canon showed off in September of 2015. Five years ago already!
Canon EF 600mm f/4L IS DO BR USM Lens Prototype Images and Details
Canon showed off the EF 600mm f/4L DO BR lens today at the Canon Expo in New York. It is substantially shorter than the current EF 600mm f/4L IS II USM lens thanks to the diffractive optics inside.…photographybay.com
At the time they had a functional prototype, and I can't imagine it takes 5 years to develop the final product. I truly think they decided to save this design for the RF mount and wait for the RF 1dx equivalent.

Most strangely, Vilacom who recommended the 800mm for the Galapagos joined 15 June for that post and hasn't logged in since.
For us the visit to the Galapagos was the adventure of a lifetime, so I encourage you in your planning. If I were to go again and took an R, a 100-500mm would replace my favourite 100-400mm and I would take TCs as well to give an option of going to longer if necessary.Thank you. I appreciate your advice. I saw your post right after I posted. I currently carry my RF 24-105 f/4L and my EF 70-300 f/4-5.6 IS II USM. This setup works for 90% of everything I do, so I’m definitely saving up for the new 100-500 for that trip (I’ve been wanting an L in that range for a long time). Can’t ever really see needing bigger glass, and if I do, I’ll rent.
I see a lot of wealthy people buying these primes for major life trips who aren‘t using their equipment for anything else. I think they’ll make Canon quite a bit of money. I think they’ll get a lot of use by videographers as well. Depending of course on the price.
I was there a while ago and I found the the 70-200 was more than enough and that I often had to swap to the 24-70. I never once put the teleconverter on the 70-200 although if I had been serious about BIF then withoutbt a doubt a longer lens would have been nice.Last year I was lucky enough to take a trip to the Galapagos Islands and I have to say I would have KILLED to have one of these lenses for that trip.

A 600 f8 would make far more sense. And it would be a great compromise but I imagin it would be north of 4kI haven't logged in this site in forever, but I've been reading a lot since the impending release of the R5/6. Really looking forward to switching from a 7D2 to the R6 myself, as long as price is right.
Anyway, I decided to post because I haven't seen anyone mention this in the recent threads about the new slow, long lenses: the initial patents that were shown had both a 600/11 and a 600/8. The leaked image of the new lineup shows what looks to be the 600 being about the same diameter as the 800 and 100-500L. Anyone but me thinking it's actually a 600/8?
If it were f11, it should have at most a 67mm front thread, given 600/11 is about 55mm. I'd expect the lens to be a fair bit thinner than the 7xmm diameter of the other 2. Having it at f8 also makes more sense for the new TCs, at least the 1.4x could be used with AF on both the 600 and 100-500L.
Discuss, lol.
