Just wondering... you guys who shoot events with the a900/hvl-f58m.
If I set the flash to adi and then decide to bounce, I understand that the camera automatically switches to ttl (which is cool). However, if I have a non-sony lens on the camera, does it also default to ttl?
ie... when i use the sigma 50, do i need to set the camera specifically to ttl, or will it switch automatically from adi?
Lastly, do I even need to worry about adi (is the ttl good enough as it is)?
