I recently posted a bug report to Apple, outlining that the new Sigma 18-35mm f/1.8 lens is displayed as Sigma 18-50mm f/2.8-4.5 DC OS HSM in Aperture. Anyone else getting this? My bug submission was not marked as a duplicate with Apple, so my post was probably the first. I have not been able to rectify this using CorrectLensEXIF either.
