-the autofocus assist DOES NOT work with flashes, when you mount a sony flash and are using standard FE-mount lenses, the camera will still try and use its awful orange light instead of the much subtler red grid from the flash. AF assist light will not work at all with alpha glass.

The sensor (which is responsible for focusing on mirrorless cameras) is blind to IR light, and therefore can't see the AF assist lights coming from the flash. That's why they're not enabled, and that's why the orange light (which is within the visible spectrum) is used instead.

However, the flash's AF assist lights SHOULD work when the LA-EA4 adapter attached (if Sony thought to check for it in firmware). I'm going to have to test that tomorrow.

Hi Gary,

looking forward to see your A7 book. The a99 is a must.

I just hope Sony listen to user this time, the A7 is a great camera with small glitches.

Best wishes.
