In light focusing through a dielectric interface, Wiersma et al. [J. Opt. Soc. Am. A14, 1482 (1997)JOAOD60740-323210.1364/JOSAA.14.001482] claim that the Debye-Wolf diffraction theory and the m-theory predict axial focal fields with "little difference." We found a possible mistake of using an inaccurate apodization factor in the m-theory integral. Here we correct the apodization factor, which then leads to better agreement on axial intensity distributions between the two theories than reported.
