So sad. It's really the only thing keeping me from wanting this lens.

I've had mine for years as well and really never had any problems with it until now. I've used it a lot less since getting the 50L. I *thought* I had read here about similar issues, but I didn't really pay attention since it hadn't been a problem for me. If it costs that much to repair it, it's not worth it. I'll just use it as a MF lens, I guess. Thanks for the info!

I think it fails because of the clutch mechanism it uses and not true ring usm.

I always try to remember to store mine with the shaft fully retracted (focus on infinity)* but now I've read this I think I'll pop on that lens hood permanently just in case.

*might make a company logo! maybe not...

Happened to me and the Canon repair cost was over 1/2 of what the lens was worth.

Me too, I think I paid about $200 for the repair. I've seen broken 50 1.4's sell on eBay for about $150, so it's a toss up whether it makes more sense to repair it or just sell it as broken. I guess it depends on whether you want to keep it or not.
