ExifTool screenshot
In Exif metadata viewer, do you have any active filters ? Look on the top, there are a tool bar with a drop-down menu. Gilles Caulier I downloaded 3 samples from different websites and tested them on Windows. All Exif metadata is displayed. As Gilles says, check the filter (it's just a wrong custom filter). The same thing with your Exiftool Screenschot a filter is set, otherwise much more information is displayed. Otherwise we need a sample image from you. Maik Sorry, I reproduced it with more details, and the conclusion is changed. I think it is not caused by the original files. All metadata readout issues were occurred on symbolic links. I have tried to extract metadata by Exiv2.exe on the symbolic link and it works well. ------------------------------ >exiv2json.exe "E:\Personal\Photos\Archives\2016SummerTrip\_DSC5190.dng" | grep "Date" Error: Directory Sony2 with 25665 entries considered invalid; not read.

Do not use symlinks on Windows. Current bug 446377 and wish here, read the post by Gilles. Maik Thanks. But the tricky thing is the JPEG looks good even it is sym linked. Do you have any plan that use ExifTool to instead Exiv2 in metadata engine? I see that we resolve a possible symlink to a complete path for the save path to Exiv2. We can try the same when loading. The question is whether it works under Windows or has side effects, for example in connection with sidecars. Maik I think symlinks are not the cause. There is currently a problem with the current version of Exiv2 and Sony cameras with the size of the embedded thumbnail preview. Depending on the image, this can be too large and cause an exception in Exiv2. See bug 446403. Please send a image to my mail to test it.

Created attachment 144139 [details] Exif Page There is no data to shown in EXIF page, but ExifTool page works well. I have tested the same image on latest official exvi2 executable, and everything works well. I have uploaded the screenshots of exif tab and exiftool tab. The sample file is beyond the size limitation of attachment, plese contact me I could send the original file to you. The photo was taken by NEX-5N, you may want to get some samples of the same camera from dpreview. The missing metadata also affected the Dates album view. It used the time of image copying to instead the CreateDate that polluted my date view.
