Corrupted photo metadata (EXIF) under iOS 26.7 except iPhones

After update to iOS 26.7 metadata / EXIF data get corrupted for camera (no information except for iPhones), exposure time (always set to 259 sec. for Canon cameras, Sony o.k.), f-stop (always set to 259 for Canon cameras, Sony o.k.) and focal length (always set to 258.99 mm for Canon cameras, Sony o.k.). Any information how to resolve this issue?
