  We firstly present a new asymptotical flat and spherically symmetric solution
in the generalized Einstein-Cartan-Kibble-Sciama (ECKS) theory of gravity and
then investigate the propagation of photon in this background. This solution
possesses three independent parameters which affect sharply photon sphere,
deflection angle of light ray and gravitational lensing. Since the condition of
existence of horizons is not inconsistent with that of photon sphere, there
exists a special case where there is horizon but no photon sphere in this
spacetime. Especially, we find that in this special case, the deflection angle
of a light ray near the event horizon tends to a finite value rather than
diverges, which is not explored in other spacetimes. We also study the strong
gravitational lensing in this spacetime with the photon sphere and then probe
how the spacetime parameters affect the coefficients in the strong field limit.
