Faraday rotation (FR) measurements performed on single crystals of samarium iron garnet (SmIG) at 1.15-{mu} wavelength in a magnetic field up to 20 kOe applied along the {l angle}210{r angle} cubic direction in the 6--77-K temperature range are reported. Abrupt changes of both spontaneous FR and FR susceptibility are evidenced at 20 and 60 K, temperatures which correspond to the three spin-reorientation transitions {l angle}210{r angle} {l angle}110{r angle} {l angle}111{r angle}; the results are compared to the FR data previously obtained for the {l angle}111{r angle} direction.
