Olympus FL-36R - How to turn off built-in flash in wireless control

[analox]

<p>Hi,<br>

 

I currently use Olympus E520 & flash FL-36R. I realize that in wireless control mode (wireless-RC), the built-in flash also fires (together with the external flash) and does contribute to the image exposure. In many cases, I really want to disable this built-in flash (like in portrait-profile).

<br>

I hear that the built-in flash needs to send some commands to the FL-36R using its light, so blocking the built-in flash's light is not possible (I tried, and the FL-36R did not fire, as expected)<br>

I'm a bit surprised that Olympus doesn't have a mode in which the built-in flash only sends commands as a pre-flash and just don't contribute to the image exposure...<br>

Anyone has an idea of what to do in this situation?<br>

Thank you & Regards<br>
