What lens hood is that ?
IIRC, both the 24-105mm's and the 24-70's hoods are petal shaped.
It looks like the lens hood I had on my 24-105mm. It was not petal shaped.
Pulled my 24-105mm's lens hood out of the bag - it's petal shaped. A quick search in Google shows the same.
both my 24-105 and 24-70 are petal shaped
