  We have measured the distribution of intrinsic ellipticities for a sample of
28 relatively face-on spiral disks. We combine H-alpha velocity fields and R
and I-band images to determine differences between kinematic and photometric
inclination and position angles, from which we estimate intrinsic ellipticities
of galaxy disks. Our findings suggest disks have a log-normal distribution of
ellipticities (mean epsilon =0.06) and span a range from epsilon= 0 (circular)
to epsilon=0.2. We are also able to construct a tight Tully-Fisher relation for
our face-on sample. We use this to assess the contribution of disk ellipticity
on the observed Tully-Fisher scatter.
