I purchased this on Amazon for firework photography when I was using a Sony α7rii, and I've only used it a few times. I don't have a camera on hand, so I can't confirm its operation, but I have confirmed that it powers on. There are only a few signs of use. It can be used with Micro USB type Sony cameras. It can be used for continuous shooting and time-lapse photography. You can connect it to the camera body or use the wireless unit for remote release. Please purchase only if you understand that this is stored and judged by an amateur. No smoking environment. No pets environment. Thank you for looking.
