I am not knowledgeable about cameras, so I cannot answer technical questions. Since I have not checked the operation with batteries inserted, I am selling this as junk. Although there is no film loaded, the shutter button reacts when the trigger is pulled. I'm not sure if it's functioning properly, but other than the self-timer on the side of the lens not working well, everything seems to operate smoothly, including the switches on both sides of the top. Both lenses can be attached and extended. One of the lenses has significant scratches and dents on the outside. There is only one pair of lens covers. Overall, there are many rust spots, scratches, and dirt; please check the images. I have only lightly sprayed it with ethanol and wiped it down. Price reduction requests and comments are welcome, but I will consider them, and I cannot promise a response. I will pack it carefully to prevent additional damage. Thank you.
