Hello, I got an EOS R100 a couple of years ago and I have been having this problem for some time now.
My RF S18-45 lens that came with it will not move when I turn the zoom ring, and there is no friction in the zoom ring either. There is also a weird offset on the lens that is causing it to lean over. Recently, I found that I could turn the zoom ring past the dot showing the storage indicator.
I need some help with this, thank you in advance.
