Dear Maintainer, =================================================================== I noticed that in a handful of cases (26 jpegs out of 529), the EXIF information as seen by exiftool was incorrect;the lens type was a list (see below) instead of a specific type. Several tests with the camera and lens showed no problem with the EXIF. I stumbled on the error and can now reproduce it; the problem is using any of the Edit->Orientation functionsin geeqie. Here is an example; after applying a rotate operation from geeqie, lens info is corrupted: 2018 => exiftool A6K01199.JPG | grep -i Lens Lens Type : E-Mount, T-Mount, Other Lens or no lens Lens Spec : E PZ 18-105mm F4 G OSS Lens Mount 2 : E-mount Lens Type 3 : Sony E PZ 18-105mm F4 G OSS Lens E-mount Version : 1.41 Lens Firmware Version : Ver.04.003 Lens Mount : E-mount Lens Format : APS-C Lens Type 2 : Sony E PZ 18-105mm F4 G OSS Lens Spec Features : E PZ G OSS Lens Info : 18-105mm f/4 Lens Model : E PZ 18-105mm F4 G OSS Lens ID : Sony E PZ 18-105mm F4 G OSS ["Apply the orientation to the image content"] (also happens with losslessly rotate functions) 2018 => exiftool A6K01199.JPG | grep -i Lens Lens Type : E-Mount, T-Mount, Other Lens or no lens Lens Spec : Unknown (01 0 1 0 0 00) Lens Mount 2 : Unknown (97) Lens Type 3 : Unknown (38213) Lens E-mount Version : 47.61 Lens Firmware Version : Ver.cf.069 Lens Mount : Unknown Lens Format : Unknown Lens Spec Features : Lens ID : Sony E 16-70mm F4 ZA OSS or Sony FE 24-70mm F4 ZA OSS or Sony E PZ 18-105mm F4 G OSS or Sony FE 24-105mm F4 G OSS or ... I have verified this does NOT happen when rotating the images with ristretto. This is a serious issue if one takes large numbers of pictures, views them and later depends on the EXIF data. ===================================================================
