As you'd expect from a prime, the distortion characteristics are much better than the kit zoom. It looks pretty good, actually, although I think there's a bit of vignetting in the lower left corner. (Note 5/19/10: it turns out that Sony shipped out preproduction 16mm lenses, so it's possible the slight vignetting is a nonissue. I'll retest when I receive the production unit. Settings: 1/100, f10, ISO 200, spot metering, AWB, Standard Creative Style)
