Any suggestions on how to stop zoom creep on a lens?

I carry my dslr with the strap on my shoulder like a black rapid strap. So even a lens like the nikon 16-85 will have zoom creep after 5 minutes of walking. My 70-300 takes less time to zoom creep.

Now besides using a silicon wristband to stop zoom creep. What are other more aesthetic ways to prevent zoom creep?

Added (1). Yes Nikon do have internal zooms. They also very expensive. Not to mention big and heavy.

Silicon wristband? What's that - never heard of that.

Keep your camera turned off when it's over your shoulder and zoomed all the way in - it won't creep if there's no power to the camera.

Besides which if you really know how to use this camera it wouldn't matter. When you bring it to your eye the first thing you should do is grab it by the lens, look through the view finder to check your framing and shoot. If you can't do that in a few seconds perhaps you need to practice a little more.

Zoom creep is just one of those things you have to live with. You won't get it on the moon as the gravity is much lower but apart from that you have very little option!

Choose your lenses carefully - Some are worse than others and some have zoom locks. Many Canon L series lenses have internal zoom (ie they retain constant length during zoom) and they don't creep at all - do Nikon do internal zoom.

I can't afford the top range lenses so I just live with it.
