monolta

Hello! I recently purchased a Minolta Xg1 camera. I believe the lens I have is 50mm? Here are the details to my purchase: Minolta XG-1 camera with 50mm F1.7 MD-Rokkor-X and Vivitar 75-300mm F4.5/5.6 macro zoom and brand new Minolta 118X flash. I'm guessing I can't use portra400 film with these...
