This is a Minolta XG-1 that was produced from 1979 to 1984. I've owned an XG-1 for 23 years. I love the XG series of Minolta cameras. They are great performers and are very flexible. Due to their age, they and their lenses can be found on Ebay very reasonably priced.
Below are a few photos I took with the camera. You can see that I've had the camera for a long time. The girl in the photo on the left (My oldest daughter, Brianne) is the little girl asleep in the photo below as well. The other two in the photo are my son, Chris and my younger daughter, Andrea.
