This is a junk item. Power was confirmed. The flash reacted when pressed. The box is in poor condition, so consider it as a bonus for packaging. No price reduction. Since this is a junk item, please use it for collection, repair, or parts. Shipping will be wrapped in newspaper and sent in a paper bag. It has been left at my parents' house for a long time. I don't have any knowledge of cameras, so I apologize, but I cannot answer questions about cameras. I will remove the dust as much as possible before shipping, but there may be some that I cannot remove completely. In the case of the lens, I may ship it as is to avoid causing scratches. Returns are not accepted due to reasons such as being broken, as this is a junk item. Please purchase if you understand that this is a junk item. There may be items that can be used occasionally, but I cannot confirm this.
