Light quantity control method selection [ALC/ELC]

The method of controlling the quantity of light is selected from the following in accordance with 
the lens to be used. 
ALC (default):  The iris of the lens is automatically adjusted in accordance with the brightness 

of a subject. Select "ALC" when using an ALC lens. 

ALC+:  Controls the quantity of light with a combination of the electronic shutter and auto iris. This 

selection is suitable at shooting a bright subject such as an outdoor subject with auto iris 
lens. Be aware that flicker may occur when a subject is under fluorescent lighting. 

ELC:  Controls the quantity of light with the electronic shutter. This selection is suitable for use 

of a lens with fixed iris or manual iris.
