reviews
-
lower dynamic range and resolution than immediate peers
raw compression can lead to posterization at high contrast edges
overly sensitive eye sensor is annoying
4K footage from APS-C region of sensor is disappointing
small battery can be restrictive, especially for video shooting
ergonomics poor for video work
-
issues with Metabones adapters
-
GH4 still has many advantages the A7S doesn’t have, like longer battery run-times, a better screen, quicker boot time and of course an internal 4K codec
