Hi, Since I upgraded to El Capitan last week if I open up an exported Nikon D750 file from Lightroom the preview EXIF no longer shows the ISO value for some reason, which is a bit frustrating. The ISO value is still displayed on my Olympus EM5-II and Sony RX100-III files though. Does anyone know why this is and if there's a solution? If I open up the Nikon RAW files the ISO value is there. Another strange thing is that when I open up the exported Nikon files in preview there's a slight stutter too, again no issue with the Olympus or Sony files. Any help appreciated.
