    Hi everybody! I've been lurking for a while and finally joined the forum. Looking forward to learning from you guys, and maybe even contributing a bit!

    Here is my first question:

    I just got my first flash - the Nissin Di 466, and was wondering whether it is possible to remotely trigger the flash via the flash of my e-pm2, without adding to the exposure.

    Thanks, Rob!

    Your answer has actually been quite helpful.

    So I learned that I have to activate RC mode on the e-pm2, where I can then set the on-camera flash to "off". I did some testing and found that the on-camera flash nonetheless adds a little to the exposure, but I guess I can live with that.

    Another trick is to put (hold or rubber band works) an piece of IR filter in front of the on-camera flash. That lets IR through, which is enough for the slave flash to fire, but it won't show up in the photo because the camera sensors has an anti-IR filter in front of it.

    Is this an issue on newer models (E-M5, E-M1)? I've not heard of the bundled flash unit causing exposure issues in RC mode for remote triggering before on newer models

    When I used EPL5 to trigger the Metz 44 I don't think there's an issue, but I'm not sure whether the camera uses a preflash or does it actually add to the exposure. Luckily now I'm using G6 and there's a option to enable or disable the on board flash
