A previous post mentioned 1:1 changing to 3: 2. Same camera, but perhaps a different problem:
Camera: SONY RX100 When shooting RAW with an aspect ratio= 4:3, the file is automatic adjusted to an aspect ratio of 3:2 when imported into Aperture. I can see the “jump” as it occurs in the viewer mode. This change does not happen with jpegs. This also happens to photos taken at 16:9 RAW as they convert to 3:2. The jpgs are not effected. Have I got a setting wrong? Or is their an error in the Apple Camera Raw software for the RX100? Import presets are “none” . Help very much appreciated.
