The 600 and 800 look like they extend in use? It has to be the weirdest lenses I've seen in a long time, right up there with Laowa's probe macro.

Looking forward to reviews of these, but may take longer if the weather is cloudy :|

Whilst I think small and lighter is going to be important (airlines getting strict) I do think f11 was maybe a stop too far? They managed a 100-500 f7.1, so why not a 600 f8. This would compete with the 4/3 system and give photographers needing light weight a reason not to invest in a new system (and the IQ would be better, much better).

All the examples Canon showed were pretty much still animals in bright sun taken at 1/200sec.

I don't get it with the f/11 lenses. Maybe these cameras are noise free at ISO 25,600?

Compact, lightweight I get that. The issue will be shutter speed for bird/wildlife photography. IS doesn't do anything to combat motion blur of a fidgety bird.

Shutter speed is not all that counts in wildlife and bird photography. The reason that the 300 f2.8 and 600 f4 lenses have always been popular for wildlife/bird photography is the shallower DOF for subject isolation from the BG. That is one of the most important things to get an image that stands out. f11 just won’t cut it for shallow DOF. BIF is a different subject. More DOF may help there to get the subject in focus, even though the focus may not be exactly spot on, but then again, the BG must be either sky or else, far away.

Looking at the price and compactness, I think they are geared for entry-level consumers. I kind of like the idea of them, it's always interesting to see a company trying something new. I think a 600f 5.6 DO lens would be awesome though.

Agreed.

I've noticed that issue since I started shooting with the Sony 200-600 f6.3 compared to my old days of using a 500 or 600f4.

DOF also depends on how far away you're from the subject. Sometimes even F11 doesn't give you enough depth of field. The distance between your target and its background also matter in the final look of your images. If there's a 600 f8 available, I think it would be popular, too.

If you’re that close, you probably don’t need a 600mm or 800mm lens.

As I understand it, these are fixed aperture lenses...??? Mirror lenses are going to stage a zombie apocalipse...

I guess, for the price, it’s hard to expect more. They do have IS and coordinate with the IBIS on select bodies. The old mirror lenses are still going for a few hundred. I sold an old Nikon 500 reflex for $200 a couple of years ago.

What if you only have a 600 or 800 with you at that time, photographing a small bird the size of a sparrow, a chickadee, or a bushtit??

If the subject is 20 ft away, a 600mm on a Nikon full frame with f11 gives you a depth of field of 2.52 inches, 6 inches if 30 feet away, and 1.38 ft if 50 feet away. If f4 is used, it's 0.84 inches, 2.04 inches, and 5.88 inches respectively.

Yes, complete with all the doughnuts! At least these new lenses wont have the doughnuts from bright spots and reflections!

At least with a variable aperture you have DOF options, unlike these lenses. If these are the only lenses a person has with them, they are probably not a serious photographer or else a beginner.
