  In this paper, we study the gravitational lensing by some black hole classes
within the non-linear electrodynamics in weak field limits. First, we calculate
an optical geometry of the non-linear electrodynamics black hole then we use
the Gauss-Bonnet theorem for finding deflection angle in weak field limits. The
effect of non-linear electrodynamics on the deflection angle in leading order
terms is studied. Furthermore, we discuss the effects of the plasma medium on
the weak deflection angle.
