Gravitational microlensing has proved to be a versatile astrophysical tool.Recently, the question of whether higher order relativistic corrections caninfluence the observable properties of microlensing has been addressed. Thisletter extends earlier studies, investigating higher order relativistic termsin astrometric shifts during microlensing events, revealing that they produceno effects. The magnitude of the relativistic corrections is examined in anastrophysical context and is found to be negligible.Comment: 4 pages (PTPTeX); accepted for publication in Prog. Theor. Phy
