Photoproduction of eta mesons off light nuclei (d, He-3, Li-7) has been measured at the tagged photon beam of the Mainz MAMI accelerator with the combined Crystal Ball/TAPS detection system. Special attention was given to the threshold behavior of the reactions in view of possible indications for the formation of (quasi-) bound eta-nucleus states, so-called eta-mesic nuclei. A very strong threshold enhancement of coherent eta photoproduction off He-3 was found and coherent eta photoproduction off Li-7 was observed for the first time. Preliminary results will be discussed.
