We shall discuss the finite ma errors of the overlap fermion in this talk. We present results on the speed of light from the dispersion relation and the hyperfine splitting between the vector and pseudoscalar mesons as a function to ma to reveal the mΛQCDa2 and m2a2 errors. We conclude from this study that one should be limited to using ma less than 0.5 in order to keep the systematic ma errors below a few percent level.
