EF-M 11-22mm f/4-5.6 IS STM not working

[MrToon]

I have an EOS M6 and the EF-M 11-22mm is not working on it. The camera shows a blinking green light and the screen has no image. When I put my 50mm lens on the camera it works just fine. Any ideas or suggestions?

Did that lens once work ok with the camera or is it recently a acquired lens?

[MrToon]

It once worked with the camera. I got the 2 lenses when I bought the camera.

Do you have a filter or other device screwed onto the front of the lens? If so, try removing it.

[MrToon]

No, no filter on it

It is looking like the lens needs to be sent in for repair. You should compare the cost of repair to a new or used lens to see if it is cost effective. 

[MrToon]

I"ll have to do that. I haven't found the lens under the cost of $399

You can get that lens refurbished from Canon right now for $320. In my experience buying a refurbished lens from Canon is practically like buying a brand new one.

I had the exact problem with a refurbished by Canon lens. I RMA'd it and the replacement is supposed to be here tomorrow. Hope this one works.

I'm having the exact same issue with my M5 and 11-22.  It started while I was using it too - just gave up.  It gives me a blinking green light for about 30 seconds with a blank screen, then the screen comes on, MF and no f/stop reading or control.  Other lenses work fine.  What did you end up doing?

Thanks!
