Sony Rx10 Mk IV Images cropped when uploaded to lightroom
When I upload my Rx10 Mk IV images to lightroom the appear in the library already slightly cropped.
I have no preselected automatic import edit settings.
I am working with full resolution RAW .ARW files which are 5472×3648 px.
The "Dimensions" appear listed at the above resolution in the metadata panel, but directly below to the right of "Cropped" it says the resolution is 5463x3642.
I can manually edit the images in the develop module to reclaim the lost pixels, but I do not want to have to do this each time I upload even w/ Lightrooms wonderful sync settings feature.
When I first cropped one of the afflicted images lightroom warned me w/ a pop up dialogue box claiming "The metadata for this photo has been changed by both Lightroom and another application. Should Lightroom import settings from disk or overwrite disk settings with those from the catalog?" I selected overwrite disk settings, and the image cropped to the appropriate size. I have never encountered this before. I called Sony support and they claimed there is no editing occuring in camera to the RAW files, so no metadata should be changed.
I tried opening images directly from the sd card into photoshop, and when I checked the image size sure enough the small crop was present (5463x3642 instead of 5472×3648).
Lastly, neither my Sony a6300 nor my a7rii have this issue on import.
This is my first time posting in an adobe forum and I hope I did this correctly. Any help would be greatly appreciated.
