Yes — for a non-destructive fix, the most practical options mentioned are friction-based.

A thick, good-quality rubber band partly overlapping the zoom ring and barrel is the simplest solution and may be enough on its own. If you need a more positive hold, adding a small spacer like a toothpick or paperclip under the band can help it catch the zoom-ring knurling more securely.

Another safe option is gaffer tape. Unlike duct tape, it’s designed to remove cleanly and can hold the zoom ring in place for static setups.

There are also purpose-made products such as silicone lens bands designed specifically to reduce zoom creep.

If this is a permanent copy-stand/rostrum setup, another workaround is to use a prime lens at the focal length you need, since a prime can’t creep.

For long unattended use, a dedicated silicone lens band or carefully applied gaffer tape is likely the most reliable non-destructive choice.
