The 600 III is lighter than the 500 II.
That is impressive. I own the 500 II, handhold it all the time.
yeah, 500 II is relatively easy to handhold. balance is great too.

Yes, unfortunately they are.Wait, are these focus by wire?
This weight reduction is just fantastic. I had the 400 2.8 IS (original version for rent, it was not handholdable, and the IS quite bad. In Comparision, just recently I could use a 400 2.8 IS ii, which is a fantastic improvement.
Now, 1 kg less (as the 300 2.8 IS) and 1.5 stops better IS, there is nothing to add, except that I don't have 12k$ of pocket money to be burned. And the big concern, what about RF (beside the possibility of using adapters) ???
Now, comparing the weight differences between 300/400 or 600/500 lenses at the same opening, a 500mm 2.8 or a 700 4.0 at below 5kg comes into sight. for a bargain of 20k bucks maybe
Yes, unfortunately they are.
Yes, slight improvement at the edges/corners (everything is at 600mm, since these are prime lenses). The MTF for the 400 MkIII should be on Canon Japan’s website (that’s where I got the MTF for the 600 III), although they don’t generally publish MTFs for lenses with TCs (with the exception of the 200-400 with it’s built-in TC).So seems like the difference in sharpness will be towards the edges and at 600mm? (am I reading it right).
AF at f/11 matters only for an f/5.6 lens with a 2x TC, so not really relevant for these f/4 lenses. A 100-400 with a 2x would AF on the EOS R (but that combo also can AF in live view on current DSLRs).I like what i'm seeing and hopefully they will have a new extender pair that comes with these lens. Since the EOS R can now autofocus at f/11 that's huge for those who use TC's.
Where are you getting the information that the 400 III and 600 III are focus-by-wire? I don’t think that’s the case.Yes, unfortunately they are.Wait, are these focus by wire?
Looking forward to 500 f/4 iii with 25% weight reduction over ii...
Where are you getting the information that the 400 III and 600 III are focus-by-wire? I don’t think that’s the case.
One will lose the feeling of direct contact with the focusing group. It is going to behave like the white ring (which I have never used) in previous versions.What does that mean for the lens and do you guys think that had anything to do with the weight reduction?
I’ve seen it reported on som non-Canon sites that these are FBW lenses.Where are you getting the information that the 400 III and 600 III are focus-by-wire? I don’t think that’s the case.
Starting from 3:00. There is even an additional switch to control the sensitivity or as they say “speed” of manual focus.
Thanks! And ugh. I saw the line in the feature list, “Improved, flexible focus control with a customizable electronic-focus ring,” but was hoping that referred to the focus preset ring which also drives Power Focus on the MkII lenses.Starting from 3:00.

Agreed. I had no plans to upgrade anyway, but this makes that even less likely. I manually focus my 600 II quite frequently, and I’m not a fan of FBW (having owned the 85/1.2L II and many EF-M lenses which are al FBW).Thanks. I did wonder when I saw those switches. I've only used focus by wire on the 85L II and I've no doubt the implementation will be better here, but I dislike it, and it would put me off upgrading even if I could afford to.
Hmm. Is this a coincidence, convergent thinking, that Sony and Canon make the same radical change of lens design within months of each other? Or do we suspect industrial espionage?Looks like they moved some elements rearwards

600/4L IS II:
600/4L IS III:
I’m not sure I’d call the MkIII worse, but based on MTF charts I’d conclude that the MkIII does not offer any meaningful improvement in sharpness or contrast. The new coatings are likely better at reducing flare (and of course, that affects contrast when present), but I haven’t found that to be an issue with the 600 II (unlike, for example, the 70-200/2.8L IS II, where despite the claims of no improvements, I expect that lens to have meaningfully better performance in backlit situations, where the MkII just washes out with veiling glare).
The DO 400mm f/4 II is significantly shorter, ~4", than the old II and the new III 400/4.No plans to upgrade, sorry. If this was a 600/4 DO, I might feel differently...
