Lens Serial Number

number, you can register only one unit of the same lens model.
Even if you enter the serial number, “ * ” will remain displayed.
 The lens serial number on the lens may differ from the serial
number displayed on the screen in step 3. This is not a
malfunction.
 If the lens serial number includes letters, enter only the numbers.
 If the lens serial number is eleven digits or longer, enter only the last
ten digits.
 The location of the serial number varies depending on the lens.
 Some lenses may not have a serial number inscribed. To register a
lens that has no serial number inscribed, enter any serial number.
 If [2: Adjust by lens] is selected and an Extender is used, the
adjustment will be registered for the lens and Extender combination.
 If 40 lenses have already been registered, a message will appear. After
you select a lens whose registration is to be erased (overwritten), you
can register another lens.
