I bet it's a 300-900mm or something to that effect.

I stand corrected.Sigma and Tamron feet already come Arca-Swiss compatible.
Aluminum oxynitride is one possibility for high refraction optical elements. This is assuming Sigma engineers have conquered the production challenges.Are there any lens optic inovations on the horizon? We would all like smaller, stronger, large aperture, cheaper, and sharper telephotos.
Hmmm,

The fact it's for sports and wildlife makes me think it will need to have a short focal length at one end if it is a zoom as not too many sports need 400+mm.If he says it will have sports and wildlife photographers interested, it has to be a relatively fast aperture (f4 or faster IMO).
f6.3 is only one third of a stop "slower" than f5.6 . As an owner of the stellar 600PF I can assure you that third of a stop makes little difference and there are no issues with it being a PF lens. Also, Sigma makes a mirrorless 500 f5.6 (though sadly not in Nikon Z mount).I would settle for a high quality 600mm f5.6, a lens I have wanted for ages, but nobody makes. Non-PF and non-f6.3...
Don't throw facts at a good joke LOLSigma and Tamron feet already come Arca-Swiss compatible.
…Long ago and far removed from many forum member’s memory was the wildly anticipated and hyped lens from Nikkor…….
Meet the first ever zoom telephoto lens…. The cutting edge 43-86mm 70’s dud! Yup, still got it…..A reminder not to get too excited about rumors…

I’ll be sure to “fact check” with you in the future…. My reference was for an interchangeable Nikkor zoom lens….The 43-86 f/3.5 first appeared in 1963 as a fixed (non-interchangeable) lens on the Mamiya-built Nikkorex Zoom 35.
My vote is for a 200-500TC F/4
One lens to rule them all
Will be rather large and heavyMy vote is for a 200-500TC F/4

I think that would have been the case 10 years ago, but lenses are getting lighter all the time. As for bulk, it can't beat physics, but it would still be a bit smaller than a 600 F/4. But man, talk about versatile!Will be rather large and heavy

It would, but it shouldn't be any larger than a 500 F/4. It would have more elements, but I'd bet it could be done in a way that kept it somewhat reasonable in weight. Lenses have gotten lighter over the years. I'd guess a modern 500 F/4 would weight just under 5 pounds based on how much trimming the 600 and 400 have seen. Granted, a zoom would be heavier, but still, I think manageable.Lenses may be getting lighter but we are getting older, It is a race to the bottom
500 F/4 will require large elements. F/4.5 or F/5 would be much more reasonable in size
Problem is Sony kneecaps them at 15 fps. That’s a no go for me.According to Yamaki San, Sigma CEO, in his answers in interview “Yes, so sports photographers and wildlife photographers might be very excited about the lens.”
