I've searched the web for an answer to this, but no definitive answer. Pre-AF OFF, AF-S, not touching any buttons, the aperture changes constantly as the light entering the lens changes: https://youtu.be/OqaF87utnlM

My questions:

Why is this required?

How will this affect the life of the aperture mechanism?

Can I turn it off.

It's a known issue. Fujifilm website has explanations, but in Japanese only. To avoid it, just manually set shutter speed. Meanwhile, please make sure "PREVIEW EXP./WB IN MANUAL MODE” in the camera menu is set to "ON".

Very interesting. I have not been able to find that "known issue" mentioned anywhere. I did notice that switching to manual shutter stops the aperture stuttering.

Try this if you can read Japanese: http://digitalcamera.support.fujifilm.jp/app/answers/detail/a_id/17361/~/%E9%9B%BB%E6%BA%90%E3%82%92%E5%85%A5%E3%82%8C%E3%82%8B%E3%81%A8%E7%B5%9E%E3%82%8A%E7%BE%BD%E3%81%8B%E3%82%89%E9%9F%B3%E3%81%8C%E3%81%99%E3%82%8B%E3%80%82
