THE DATA BACK IS QUITE USEFUL, ESPECIALLY THAT IT WILL BE IN PRINT IN BETWEEN THE FILM, HOWEVER, SOMETIME WHEN DEVELOPING THE FILE THE MACHINE MAY NOT RECONISED THE GAP BETWEEN THE FILE AND WILL THE THE PHOTO INCORRECTLY. THIS IS NOT A PROBLEM FOR ME AS I ONLY USE THE SMALL PRINT TO SCAN FOR ENLARGE.
Thanx for understanding my bad English first. Just want to add that since I have posted that question in this forum, I called B&H, and they confirmed that Data Back imprints only date info (time, day,etc.)I think that price for only this feature (date info) is a little bit exagerated.
