One of the best tests for compositeness of leptons or quarks is the presence of an anomalous magnetic moment F2. We determine limits on F2 for the, from e+e-+- at PETRA, of F2<~0.02. We also present limits on the F2 of the quarks. We suggest lower-energy experiments on the angular distribution to give an independent measurement of F2. Future experiments near the Z0 peak are discussed. © 1983 The American Physical Society.
