Fujifilm Remote Release RR-90
The RR-90 Remote Release is a wired shutter release designed for use with select FUJIFILM digital cameras. Mimicking the same controls as the camera's shutter release, this remote supports half-pressing for focus and full pressing for exposures. Additionally, the release button can be locked into position to support making long exposures in bulb mode.
