This is a compatible product for the SONY ADP-AMA. I purchased this several years ago and have kept it in storage without using it. It is compatible with SONY α series cameras and auto-lock accessory shoes. This is a hot shoe adapter exclusively for SONY α series cameras. Inserting it into the camera's hot shoe connects the circuit to the X contact on the side of the adapter. Note 1: It does not support TTL auto or pre-flash. Also, it is not compatible with strobes with high sync voltages, such as older models. Note 2: Even with strobes with low sync voltages, there may be compatibility issues between products, and they may not function. Please check in advance. (Nissin strobes and National PE series models cannot be used.) This is considered a rare item. It is compatible with the auto-lock accessory shoe adopted from Minolta/Sony α series SLR cameras α7700i (1987) to Sony α77 and NEX-7. It has a sync cord input terminal. Photo 9 There is a small dent on the corner from the time of purchase, but there are no other noticeable scratches. Immediate purchase is OK. Thank you.
