p.1 #1 · p.1 #1 · Better way to fix zoom creep for push-pull zooms?


Hi,

I have a few old MF zoom lenses that I like a lot. They are of the push-pull type and all have the zoom creep issue. SInce they are push-pul type, I think the lens-band will not fix. So I'm looking at putting on a tape. I just wondering which kind tape may be best? Or you have other suggestions?

Thanks,

Eric

Gaffers works great. Usually you'll just need a thin strip on the underside of
the barrel...along it's length, to take care of the creep.

Nikon lenses have pretty tight barrels, so the tape method works well. Most 3rd party lenses have too large of a space for tape to have an effect. I use Dymo labeling tape. It's hard, waterproof and permanent. This what it looks like on the 75-150, a lens notorious for creep. It's important to tuck the tape under the fully extended barrel as far as you can.

Looks very good. Mine is a newly bought but very sharp Nikon 80-200 f4.5 AI lens. The zoom ring creep like a free fall object.

Is this tape easy to remove if I need to adjust its position?

I simply let them creep. I often use the 80-200 f/4.5 AI when shooting with tubes and I love the very free play of the zoom ring as I find focus. I don't even try to turn the focusing ring, I simply slip it forward and back. I know tape works, but when I'm shooting the fingers of my left hand are always on the focusing/zoom ring, so I can put the ring exactly where I want it. I guess if you're mounting it on a tripod and using a remote trigger you'd want the lens to hold position, but that isn't how I use these lenses... just to offer a contrary opinion on the subject...

Good luck sorting this out. If you're shooting with a Nikon camera and have one of these old lenses mounted, you might want to post a photo or two on the Manual Focus Nikon Glass thread. We're having a great time celebrating these old lenses.

I didn't really think of leave it as is. But it's certainly a valid way to deal with it. Thanks very much.

It come off fairly easily and doesn't leave any residue. Once off you have to replace with new.
