A friend of mine has an old Minolta X-7A that he would like to start using again and there are no batteries in it. He doesn't have a manual and the batteries were removed a while ago to be replaced and never were. Does anyone who know what batteries this model takes? I thought it might be 2 -CR-5's but I'm not sure and I don't know anything about Minolta's line of cameras. Thanks for any help on this.
