The method of QCD sum rules in the presence of external elctromagnetic fields is used to calculate the $\Omega$ magnetic moment $\mu_{\Omega^-}$ and $\Sigma^0$-$\Lambda$ transition magnetic moment $\mu_{\Sigma^0\Lambda}$, with the susceptibilities obtained previously from the study of octet baryon magnetic moments. The results $\mu_{\Omega^-}=-1.92\mu_N$ and $\mu_{\Sigma^0\Lambda}=1.5\mu_N$ are in good agreement with the recent experimental data.
