Several reports indicate that early and pre-production models have zoom creep WHILE a newer version does NOT on both smooth and tight mode. It seems Sony fixed this issue for latter version as several people reported this on Facebook.
I guess it was a lens issue and I was right all along.
Not true. My friend just received his from the latest batch. Creeps.
Another forum member on a different forum had one on release day that doesn't creep on Smooth.
It is a tolerance issue. If you are someone who likes to zoom while shooting (say like a BIF acquiring zoomed out and zooming in as it approaches) then you will actually want to get one that creeps on Smooth.
It is still easy to zoom this lens on the Tight setting if it is a lens that creeps. But it is better on Smooth if you are actively zooming a lot during shooting. I haven't tried a lens that doesn't creep on Smooth but I can only assume it will be tighter on both settings so the Tight may become mostly useless and the Smooth won't really be smooth enough. I don't know for sure until I try one.
I'd also wonder if those that have a lens that doesn't creep out of the box will have creep after a few months of use?? The only worry I would have if a creeping lens on smooth would eventually creep on tight. That would be a flaw IMO. But only time will tell on that one.
I'd also point out that if people who haven't used the new lens are thinking along the lines of the "old" 100-400's tightening ring it is not similar to how this one behaves.
The old 100-400 on tight is almost impossible to zoom. The new 100-400 on Tight is a better lens to zoom than the old 100-400 on Smoothest. The only nice thing on the old one is it is not two fixed settings but a range of tightness along the ring. But I always said that the old one is not smooth enough on the smooth setting. This new lens is smooth enough...although in a perfect world the Smooth setting on the new lens would be even smoother like the 200-600. Of course it would creep even faster if that were the case.

I’m sensing a bit of copium being administered by folks who presume that zoom creep is just fine. If it were intentional on Sony’s part, it would affect all units equally. If the reports that it only affects some are accurate, then we’re looking at something that Sony must fix, one way or the other.
I still think it sounds like a great lens, and I intend to buy one.
While the zoom movement is suboptimal in comparison to the 200-600 and the OM 150-400, there is nothing Sony needs to fix in the units it has produced. There is quite a bit of glass and metal to move in the 100-400, as there is with external telephoto zooms. AFAIK they all have a zoom tighten/lock capability to throttle or prevent inadvertent zoom movement when the lenses are not in a horizontal position. Most reviewers have discussed the 100-400's zoom movement characteristics since day one of the lens being made public.

Then he got the early version. Clearly, if the internal zoom lens creep, then it means the lens design is faulty from the beginning.
My $.02 on the creeping. I think it’s inherent to the design. Otherwise, Sony would not have included a tight/smooth switch on the lens. Neither the 200-600 or the 400-800 have such a switch.
Why didn’t Sony design it not to creep like the other internal zoom lenses? I can speculate, but I honestly don’t know
I doubt the creep can be mitigated in future lenses without some design changes. And manufacturing tolerances appear to have an effect on how much each individual lens creeps. And just like external zooms, the creep will most likely increase over time
Is a deal breaker? Don’t know. I guess that depends on the individual and their case use. Personally I have historically favored internal zooms (even though they are larger when not in use) because of the lack of creep, smooth zoom operation, etc…
I think I would need to try one out before making a final decision. So I would definitely purchase from a place with a decent return policy
Other than the creep, it appears to be excellent lens

IMHO, the ones that creep are likely more ideal in terms of in the field function than the ones that don't. But again I haven't held one that doesn't so can't say for sure. I'm making an assumption that in order to not creep it will be less smooth on the smooth setting. Something I don't want at all.
Now, if Sony had a version that was as smooth or smoother on the Smooth setting than the lens I own but didn't creep at all I'd say that was a win.
If a lens that creeps in the smooth setting is a fault for you then I wouldn't buy this lens unless you can verify a copy at a store or through the used market that doesn't creep.

If the creep was present on all of these 100-400mm lenses (or on none of them), I’d be with you. But if the reports that it affects only some lenses turn out to be accurate it seems likely that it is a design or manufacturing flaw that Sony should address.
It should not be a crapshoot whether you get a copy that creeps or not. I cannot believe that Sony would intend for that randomness to be the case.

Yes, ideally people who have one that doesn't creep should be sending it in to have it loosened.
That is what I'd do if I had a non creeping lens. I don't want a lens that is any tighter on Smooth than my creeping lens is.
Whether Sony could have designed the lens to turn as smooth or smoother than the creeping ones do AND not creep at all is something we just don't know. If they could have then they should have.
But at this point it is what it is. One could try and contact Sony about it and see how far they get. I'm not sure what one would be requesting though? A totally new design to the zoom mechanism? Lighter elements? A new placement of the elements?
I'm glad the lens is a hit with some of you. I want Sony to lead the pack. However, I wonder what the response had been if Sony (not the "influencers") had announced the creep issue and the switch to combat the creep? I rented a 100-400 and It crept unless I turned the dial all the way. I ended up liking the lens and could stop the creep by turning it only slightly. I wonder if the new lens will end up the same way, that, over time, it will need more friction to stop the creep?
So are you guys saying there are only 2 settings for zoom control as opposed to the ring that could be adjusted anywhere between smooth and firm on the old lens?

The fact that it reportedly affects some units but not others suggests that this is more likely a design or manufacturing flaw. I cannot imagine that a company like Sony would not intend the lens to work only one of these two ways. If they intended it to be loose enough to creep, then ALL copies should work that way. If they did not intend that it would creep, then no copies should do that.
At some point Sony will have to address this question, and I believe that they will.
(Personally, I’m not buying the idea that a lens must creep in order to have a smooth and effective zoom mechanism. I’ve never heard of another lens where new copies behaved this way.)
To be clear, I think it sounds like a really excellent lens, and at this point I intend to buy one eventually.

Yes. It is not a ring like the 100-400 f/4.5-5.6 GM. It is a switch between "Smooth" and "Tight".
But unlike the older 100-400 the tight setting still allows you to easily zoom the lens, it just prevents any creep. On the Smooth setting there is much less resistance to zooming so can be manipulated quicker during action. But for most people, just leaving it on Tight will be perfect and you won't have to worry about it ending up at 100mm without you realizing when going to take your next shot.

I honestly think the intention was for it to creep because otherwise having the switch is sort of pointless. If it was not meant to creep on the Smooth setting then there would be no need for the switch. This is because it is not like the "old" 100-400GM where the Tight setting locked it very tight. The tight setting on the new 100-400 just eliminates the creep but still allows easy zooming (just not as easy as on Smooth).

That’s an interesting point of view, and I hope that someone from Sony will clarify if the intended behavior is to creep or not to creep.
I’m not so sure about your analysis. I can see it both ways. I have had a couple of Canon 100-400mm zooms (two versions) that had a ring you can turn to “lock” the zoom mechanism. These are the alternate extending zoom (or “telescoping”) design. I don’t notice “creep” (at least on the newer of the two) in the unlocked position, though on this lens the tighter position is intended to lock the lens, not just add friction to it during normal operation.
In any case, we’re all just speculating until Sony says something about this. And whether the creep is intentional or not, if it is true that some copies do it and other do not, there is a manufacturing/design issue that Sony needs to fix, one way or the other.
I don’t think there’s a lot more to say about this without clarification from Sony, so I’ll try to resist continuing the back-and-forth. :-)
