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.
