The device consists of an electromagnet moving ferronickel optical shutter interposed in a fiber gap, and it's actuation causes optical attenuation.

这种光衰减器是由电磁驱动插在两对准单模光纤间隙中的挡光片来实现光功率的衰减。

Fujifilm claims they've worked through the pixel noise problems that can accompany massive megapixel sensors (we'll have to see about that), but at the very least the S9000 has a 10.7x optical zoom lens, a 1.8-inch tilting LCD screen, a 0.01 second shutter lag time, dual xD and CompactFlash memory card slots, and can capture RAW images.
