Thank you for viewing. This item belonged to my father. I confirmed the strobe's operation before listing it, but it is being sold as-is. The power turned on, but I haven't attached it to a camera. I believe it's for Nikon. I'm also selling other camera equipment that is no longer needed. I don't know which items are for which, so I may not be able to answer detailed questions. Please refrain from purchasing if you are overly concerned about details. This is based on my personal assessment, so please understand. Due to measures to prevent switching of items, returns are not accepted for customer convenience. Please only purchase if you understand and accept the item being sold as-is.
