Hi. I've read some of the previous threads regarding issues with autofocusing on this particular lens, but I think that my problem is somewhat different.
When I turn on the camera, 5D III, the lens immediately starts hunting/clicking, and when I say hunting, I mean hunting. I sounds like someone castagnettes in a certain rythm four clicks, 1. sek. pause, four clicks and so on. It's still clicking while the camera is cleaning the sensor... When I point the camera downwards the clicking/hunting stops and when I bring the camera back to horisontal, no clicking until I half press the trigger, and it starts again. Viewfinder or screen, all the same.
I think that I've tried it all; all different programmes, different distance setting, AF or MF, stabilizer on/off, manually setting focus and no problem with my other lenses... I'ts all no-go. I'm aware that this is somewhat a technical problem, but anyone out there experienced the same.
Have a nice day - Regards Steffen

Sounds like you need to send it to your local repair shop. Do you have another camera to try?

The only one I could try it on was a 1DS II and the problem was the same, but not so hefty, so you're right, we probably have to visit the lens doctor 😞

You are doing a whole heck of a lot better than I would do in your native language!

Can't help you much with the lens as it probably needs professional service but you did mispell "whenever. Hope that helps.

I agree that you need to have the lens checked out. I have that lens and have used mine on a 6Dii, a 90D, an R, and an R5 with no problems whatsoever.
