Thank you for viewing. This is the aodelan LANC remote control "ZC-4". It has the same functions as SONY's "RM-30BP" +α. With its dedicated wireless function, it can control up to 4 professional cameras. (3 wired + 1 wireless) Although it is new and unused, it has been opened and the basic operations have been confirmed. The latest firmware has been updated. The 6th image shows the included items. ※ Some functions may not work depending on the camera. ※ Although not all functions have been checked, the minimum operations are working fine with professional cameras. ※ The included manual is only in English/Chinese. Because it is a specialized device, purchase is recommended for those with sufficient knowledge. Please ask if you have any questions. Please purchase with your understanding and acknowledgment. Please refrain from purchasing if you are overly concerned about details.
