Recent parametrizations of the photon's parton content are examined and compared. The sensitivity of the photon structure function on the QCD scale parameter is reconsidered.8 pages, LateX, 8 figures (not included, hardcopies available upon request), LMU-11/94High Energy Physics - Phenomenologytext
