Lot of Vintage 35mm Cameras & Equipment Minolta Yashica Yunon Vivitar Zeikos

Up for auction is a lot of vintage 35mm cameras and equipment. The cameras include a Yunon YN500, a Minolta XG-1, and a Yashica Electro 35. Also included is a Zeikos super wide angle lens, Vivitar auto 2600 flash, Focal M-200 flash, & a Minolta Maxxum 1800 AF flash. A carrying bag is also included. I picked these up at an estate auction, so I don't know their history. I also know nothing about cameras, so the information I've provided came directly from the cameras themselves. See pictures for further information.
