A 600/4 at ~3 kg is about the same weight as 500/4 lenses used to be a few years back. Canon and Sony(?) have both done very well here, making 600/4 lenses easier to use at least physically. This could in the longer run make 600/4 lenses more popular, maybe influencing their pricing and that of 500/4 lenses.
I still find it remarkable what Canon and Sony (?) have done with weight in the 400 and 600 lenses without using DO/PF. But the downside is still the physical size of a 600/4.
The ideal lens to me would be the 600 f/4 DO Canon showed off back in 2015....should be even lighter and is much shorter....unfortunately that seems to have been left on the drawing board and if it ever comes will likely be RF mount and will have to be mounted on some sub-standard camera.
Is there some tradeoff with or limitation to the DO/PF technology? Note how these lenses are one f-stop slower than the fastest alternatives in their respective focal lengths.
300/4 PF instead of 300/2.8
400/4 DO instead of 400/2,8
500/5.6 PF instead of 500/4
