Hi all, when i use my 90mm it makes a weird sound when i turn on shake reduction. I bought the lens 2nd hand and still has warranty on it. Is this sound normal? (Watch video)

Do you have a 90mm as well?

No, but I've worked with the 645 system as an assistant and handled two copies of the 90mm. None of them gave any audible feedback upon flipping the SR on/off switch, so something isn't quite right.
