I now have a Nikkor 'one handed' zoom (twist to focus, pull in to zoom) and it doesn't so much have zoom creep as zoom free-fall Smile if the lens is pointed downwards. Its usable for roughly horizontal shots and completely unusable for camera-pointing-down macro work.

What provides the resistance normally and how much of a job is it to improve this on an older lens?

I think it's a mix of quality of the build + characteristics of the grease.

The Contax 35-70 that I bought was surely used (I can tell from paint loss on the rim of the barrel), but absolutely has no creep.
The 28-85 Yashica that I bought last month looks used the same way, but it's a bit creepy.
So I think it boils down to build quality. And it's part of the price difference between a lens like a Contax and one like a Yashica.

Longer (100+mm) push/pull Nikon/Nikkors are famous for this problem. I hate to say it, but this is currently why I don't own any of them...

So, which lens is it that you have?


Sorry, should have said. (Its in my signature, but that will change over time)

Zoom-Nikkor 80-200 f/4.5 AiS

The really infamous one is the 70-150 E Series.

The only solution I've come across is to pull back then affix a line of tape along the barrel.
