The Olympus RM-CB1 Remote Cable Release is an ideal choice for allowing longer exposures without shaking the camera. It also helps in locking on for bulb exposures. This excellent device is compatible with E-1, E-3, E-10 and E-20N, while it works well for C-5060 & C-7070 using the Power Battery Holder B-HLD20. It is also compatible for C-8080 Wide Zoom by using the Power Battery Holder B-HLD30 or Evolt (E-300) using the Power Battery Holder HLD-3. It helps in preventing the camera shake and resulting image blur by releasing the shutter through the wired remote cable release.
