+Keep in mind that in this case, the transferred files are saved in the */home/pi/[CAMERA MODEL]* directory on the system storage card. Make sure that the card you use with Raspberry Pi has adequate storage capacity.
 
 **Important** Make sure that the camera is set to the MTP USB connection mode.
 
+### Alternative Direct File Transfer Script
+
+Some cameras (notably Sony Alpha models) may not work with the default direct file transfer script. In this case, try the *gphoto-backup-alt.sh* script instead by enabling the following cron job as described above:
+
+    #@reboot sudo /home/pi/little-backup-box/gphoto-backup-alt.sh > /home/pi/gphoto-backup-alt.log
+
+This script saves transferred files in the */home/pi/BACKUP* directory.

 ## Usage
 
 1. Boot the Raspberry Pi
