AUTOMATED FUNCTIONS
About automated functions
For documentaries and events requiring maximum mobility, automated functions such as Auto Focus and Auto Exposure reduce
the workload so that you can concentrate on tracking the subject.
The 11 x powered zoom lens and E-Mount lens supplied with the NEX-EA50 are compatible with Auto Focus and Auto Exposure.
A-Mount lenses also support the following automated functions when used in conjunction with the LA-EA1 or LA-EA2 mount
adaptor.

Video Settings
AUTO EXPOSURE (AE) function lets you control
image brightness automatically
Moving the AUTO/MANUAL switch to AUTO enables automatic
adjustments of the iris, gain, shutter speed and white balance
settings. You can start shooting right away without checking
those settings.
AUTO EXPOSURE (AE) is a camcorder function that controls
all or some of the iris, shutter speed and gain parameters
automatically to achieve ideal brightness for videos.
With the NEX-EA50, the above parameters, as well as white
balance, are controlled automatically when the AUTO/MANUAL
switch is moved to AUTO. Please note that automatic control
of iris is only possible when an E-mount lens is used. When
another maker's lens is used, iris remains under manual
control, while other parameters are adjusted automatically.
When the AUTO/MANUAL switch is in the MANUAL position,
pressing the specific button for a particular parameter, such
as the GAIN button, lets you switch between the AUTO and
MANUAL modes just for that parameter (gain in the case of the
button). The [A] icon next to a parameter indicates it is being
controlled automatically.
Even when the AE function is used, it cannot produce perfect
results under all lighting conditions. But by also utilizing
support functions, you can use the AE function effectively.
