Canon 55-250mm IS image stabilisation won’t turn off

[Astro NGC]

 

I have a Canon EF-S 55-250mm IS lens (with a canon EOS 100D) and I have noticed that the image stabilisation turns on whenever the  live view mode turns on (even when the stabiliser is turned off on the lens). When I switch off live view, it sometimes turns off and sometimes it stays on and I think it is messing up a lot of my long exposure photos. I’ve attached a photo of what one of the images looked like (although it normally isn’t that bad)

Is there any way to stop this from happening so I can use the lens at 250mm?0

Manual mode?

Is there a menu item for the image stabilisation that you can turn off as well?

I looked through the menu and I can't find anything relating to image stabilisation

Have you turned off live view and taken an image to verify a difference in behavior?

I know that in live view on my Cannon T3i, I can't trigger an on-camera flash for some reason.  Once I turn off live view, it works fine.

I'm somewhat confused as the Canon 100D doesn't have built in IS in any form!

Are you sure your lens IS is working, or more importantly not working when you switch it off.

You can try cleaning the contacts on Lens and Camera. Also update the firmware on the Camera.  Do you have other Lenses with IS that work OK on the Camera? Also maybe a friend has a DSLR you can try the lens on.

yes, the lens switch doesn't seem to be turning lens IS off

it seems to make the noise when the IS is switched off, but not when it is switched on (when taking a picture in viewfinder mode) so now I'm not sure whether it is IS or not. (it is definitely not autofocus either)

when live view is on and when taking a picture in live view mode it always makes the noise

it doesn't seem to help, the only other lens I have with IS doesn't make a noise

having tested it last night under clear skies, the switch seems to work properly, despite the noise. so I guess I just have to ignore it.

thank you for the replies
