I just received my copy of the 90mm F2 also and had a quick question if anyone can answer it. If the lens is turned off it makes a
rattling noise on the inside. When the camera is turned on and the lens is ready to shoot the noise stops. I wanted to see if this had
anything to do with 4 magnets on the inside of the lens powering the lens motor. I have not seen or read anything about this yet.
I also called the Fuji USA helpline but they did not even have a copy of the lens to verify this.
