SUMMARY
When using manual focus lenses on Fujifilm cameras, the EXIF data often incorrectly states the focal length as 21mm. This discrepancy occurs regardless of the actual focal length of the lens being used. The issue appears to be related to how Fujifilm cameras process metadata from non-native lenses. This phenomenon affects users who rely on EXIF data for cataloging or analyzing their photographic work.
