Sony ILCE-7S - Manual (Page 89)

It is recommended that you adjust the position under actual shooting conditions.
When you attach a lens for which you have already registered a value, the registered
value appears on the screen. [±0] appears for lenses for which a value has not yet been
registered.
If
[−] is displayed as the value, then a total of 30 lenses have been registered and no new
lens can be registered. To register a new lens, attach a lens for which the registration can
be erased, and set its value to [±0], or reset the values of all the lenses using [Clear].
If you perform [AF Micro Adj.] with lenses other than Sony, Minolta, or Konica-Minolta
lenses, the registered settings for Sony, Minolta, or Konica-Minolta lenses may be
affected. Do not perform [AF Micro Adj.] with an unsupported lens.
You cannot set [AF Micro Adj.] individually for a Sony, Minolta, and Konica-Minolta lens of
the same specification.
