A Polaroid instant camera with an autofocus function. It's the "Polaroid Land Camera Sonar AutoFocus 5000". It was stored at my grandmother's house. I don't have much knowledge, so this information is based on my research. Please refrain from purchasing if you are overly concerned about details. Only those who understand that this is a stored item are welcome to purchase. The following is information about this camera: Features: Developed by Edwin Land, the founder of Polaroid, as an instant camera that can develop monochrome photos in 60 seconds. Film: This model uses roll-type Polaroid film, but if a Polaroid back is attached to the back cover, 85x108mm 10-sheet pack Polaroid film can also be used. History: Polaroid stopped producing instant cameras in 2008, but instant cameras like "Cheki" have continued to play a unique role. Development Background: It is said that the development was triggered by Edwin Land's response to his daughter's question, "Why can't I see the picture right away?" Development in Japan: From 1960, Yashica started manufacturing Polaroid 120 and Polaroid 160, which were sold and exported in Japan.
