I'm afraid my new Canon RF 24-70 lens may already be acting up. There's a constant whirring sound coming from it which I'm fairly certain is the image stabilization. Thing is, the sound is always there, even when the IS switch is set to "off." Having the camera set to auto or manual focus made no difference either.

This was not the case with my other two Tamron EF lenses.

I'm curious if this is how all RF lenses act, or it's just mine.

Is it possible you have the camera set on af continues on ?

then the lens wil try to focus all the time

page 278 of the manual 1.10

Yes, it was disabled. Having it on or off makes no difference.

After further research it looks like this is simply how the IS system was designed.

See this thread here: https://www.dpreview.com/forums/thread/4457853

I also reached out to Canon support and they confirmed that is the case. This was their response:

Per design of RF lenses, the sound you are hearing is from the image stabilization motors which are still engaged. Per design by Canon they will continue running though not providing any stabilization if image stabilization has been turned off. Please note this is present on different RF lenses.

I'm just glad there's nothing wrong with my lens.
