This is an update on my review a few days ago. The Hähnel Captur wireless Camera Remote Control transmitter receiver that was delvered a few days ago now work flawlessly on my Olympus OM-D E-M! Mark II camera. The problems I encountered, were due to wrong informatiion in the User Manual. The Manual states that the TRSS cable bundled with the Captur transmitter / receiver should be used for aquiring focus and for trigging the shutter. When using the TRSS cable, nothing happens, and I thought that the Hähnel Camera Remote Control was faulty. Today tried the TRS cable that also was delivered with the Captur transmitter / receiver, and the problem was solved. Speed Graphic, who sold me the Remote, responded quickly and professional, and I will give the company my best recommendations.
