A lens I use frequently has developed a manual focus ring that turns too easily. What are the safest low-cost ways to deal with a loose focus ring, and is this something worth sending in for service rather than trying a DIY fix?

Personally, I'd at least ask for a free quote from Olympus, especially if this is a lens you use frequently. It may be much cheaper than you anticipated and would be a more permanent solution than trying to fix it yourself with glue and such. Here's the website repair page.

I shoot Canon and was hesitant to send in a lens for repair because of the cost, but it made a big difference in the end.

The safest long-term fix is to have the lens inspected or repaired by the manufacturer or a qualified repair shop. A loose focus ring usually means wear in the ring or internal friction parts, and a proper repair is more reliable than DIY glue or disassembly.

If you want a temporary, low-cost workaround, adding external friction can help. A wide rubber band or similar sleeve around the focus ring/barrel joint may make the ring harder to turn accidentally. Keep any adhesive off moving parts and away from the lens body unless you’re certain it won’t interfere.

In short: for a durable solution, get a repair quote first; for a quick temporary fix, use a rubber grip/friction band rather than attempting internal repair.
