This is a remote release with a φ2.5mm terminal. Similar to the camera, pressing the shutter button halfway focuses the lens, and pressing it fully takes the picture. For bulb shooting or continuous shooting, you can slide and lock the shutter button. ＜Compatible Models＞ GFX100 II / GFX100 / GFX100S II / GFX100S / GFX50S II / GFX 50S / GFX 50R / GFX100RF / X-H2S / X-H2 / X-H1 / X-Pro3 / X-Pro2 / X-T5 / X-T4 / X-T3 / X-T2 / X-T1 / X-S20 / X-S10 / X-T50 / X-T30 III / X-T30 II / X-T30 / X-T20 / X-T10 / X-T200 / X-T100 / X-E5 / X-E4 / X-E3 / X-M5 / X-E2 / X-E1 / X-A7 / X-A5 / X100VI / X100V / X100F / X70 / X30 / XF10 / GFX ETERNA 55 / Remote Release RR-100 ※ For use with GFX100 II / GFX100RF / X-T50 / X-S20 / X-S10 / X-E5 / X-E4 / X-T200 / X-M5, a commercially available Φ2.5mm-Φ3.5mm conversion adapter is required.
