Hello! I recently bought a Yashica FX2 with a 50mill lens at a pawn shop for $50. I need to know what other lenses this body will accept. I am interested in 100 and 200 prime lenses, preferably used. How much can I (should I) expect to pay for such lenses. This is my first SLR camera and I am very happy with it. ( I learned how to use a SLR in college, namely a Pentax K1000.)
