    I have a Yongnuo YN462 single-pin manual flash unit that works on a GF2 but not on a OM-D (on hotshoe), does anybody have similar experience? Is an Oly/Panny external flash required on OM-D?

    What shutter speeds did you set for your high and low flash sync ?

    the default is 1/250 for high and 1/60 for low, I changed the high to 1/160 still no flash. It does flash once while sliding into the hotshoe but the flash icon is grey out, and would not flash when shutter is pressed. There's no flash icon showing so it seems like it's not recognizing the flash, while GF2 does.

    Do you have "fill flash" selected in the Live View or SCP screen ? 1/60 low and 1/250 high sync speed are probably the preferred shutter speed settings.

    Did you engage the flash mode on the camera?

    yes, I use the same procedure as with the mini flash, the mini flash works but this doesn't. I don't understand how could this work on GF2 and not on OM-D.

    Nope not required. I actually make more use of older flashes (mostly Sunpaks) than flashes that TTL. In fact, I have the exact opposite problem. My Olympus FL300R does not work on the OMD hotshoe but my sunpak does.

    My flashes do not illuminate the flash symbol on the OMD but trigger just fine..... i think that only happens with olympus TTL flashes.

    Sounds like OM-D is selective on external flashes on hotshoe...

    Must be something with Yongnuo flashes. I use the supplied mini flash, FL36R, FL-300R, OM T-32's, Om T-10, Nikon SB-26's & Nikon SB-800's with no problem.

    Did you figure out why the FL-300R would not work on hotshoe?

    I think at least some OM-Ds has this hotshoe flash problem. I met up with someone on craigslist with a FL-36 thinking that OEM flash should work on OM-D, the flash unit detected the focal length of the lens, however, it simply could not flash at all on my OM-D's hotshoe (just like the YN-462, when it slides into the hotshoe it would flash once but never flashes when shutter is pressed). For reference the FL-LM2 works just fine on my OM-D. Does any OM-D user with oly/non-oly external flash encounter this problem? For my OM-D the only working external flash so far is the FL-LM2 and this is disappointing.:frown:

    OM-D Hot-Shoe issue

    See my post here:
    https://www.mu-43.com/f67/fl-300r-omd-25902/index2.html

    The non-Oly flash I tested is a Nikon SB-26, which worked in Manual mode as directed in the OM-D instructions. The 300R required the described kludgy workaround to register with the camera. While registered it works fine.

    OM-D Hot-Shoe issue

    I think I know the cause & a solution for this issue:

    For me, the more I used the FL-300R on the hot-shoe, the more reliable it became. I realized that the "break-in" was helping remove whatever contact-breaking "glaze" there may have been on the bared metal portion of the inside edge of the OM-D hot-shoe rails. I cleaned these further (gentle scraping with an exacto knife, or fine sandpaper), and now the operation is flawless; no more break in contact or lack of registration.

    I still haven't gotten it to work...

    Its currently spending most of its time on my LX3's hotshoe.

    The FL-300R *does* complement the LX3 nicely!

    I guess there are multiple reasons an external flash might not register for some OM-D hot-shoes. I had seen that this could also be a problem on a few E-P3s & E-PL2s.

    im guessing you guys double check voltage first in your camera and flashes right?. +/- 1V difference could f*** up either you flash or camera for life.

    here it always comes handy! http://www.botzilla.com/photo/strobeVolts.html

    Why wouldn't a flash designed for the particular camera not work with that camera? You are familiar with the flash and cameras we're talking about here, aren't you? They are compatible with Olympus/Panasonic flashes, which use the same TTL standard. There's no need to go to that site you mentioned.

    Anyway that site has to do with flash trigger voltages, not TTL voltages.
