  Conformal Weyl Gravity (CWG) predicts galactic rotation curves without
invoking dark matter. This makes CWG an interesting candidate theory as an
alternative to GR. This removal of the necessity of dark matter arises because
the exact exterior solution in CWG for a static, spherically symmetric source
provides a linear potential $\gamma r$, which can explain the observed galactic
rotation curves with a value for $\gamma$ given by $\sim + 10^{-26}
\mathrm{m}^{-1}$. Previous work has also shown that CWG can explain lensing
observations, but with $\gamma\sim - 10^{-26} \mathrm{m}^{-1}$ in order to
ensure converging rays of light rather than diverging ones. Even though
different expressions for the angle of deflection have been derived in CWG in
order to remove this inconsistency, this paper shows that the $\gamma$ required
to fit the lensing data is several orders of magnitude higher than that
required to fit the galactic rotation curves.
