The camera needs to be set to function without an E-Mount lens attached. You can do this by changing the following camera setting: 'Menu' -> 'Setup' -> 'Release w/o Lens' -> 'Enable' (Exact naming and location of this option may change depending on camera model). If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.
