    I'd like to share with fellow forum members that I've tested E-P5 with manual Nikon SB-30 flash (no TTL contacts) and found that the true flash sync to be 1/500s in native 4:3 ratio or 1/640 in cropped 3:2 ratio. This is extremely useful when shooting in the sun at wide apertures. Even in the brightest sun, 3-stop ND filter will be sufficient to utilize f1.8 and even 1.4 and use flash without resorting to FP/HSS which reduces the flash power dramatically. This compares favorably to E-PM2 and E-PL2 which have true flash sync 1/320s in 4:3 and 1/400s in 3:2. I don't know about you but I prefer fully manual flash when shooting outdoors. Olympus cripples TTL flashes to 1/250s or slower...

    You haven't tested the E-M5 have you?

    How did you trigger it? On camera, with a cord, radio trigger (which ones?), slave mode or in which way? This would really be interesting since I'm still using a set of Yongnuo RF 602 and they are way to slow on the Olympus so I'm looking for a good alterantive to them.

    Was the flash on full power?

    I've got so far the best results with the E-M10 using the inbuild flash in rc mode as trigger. This could sync a Yongnuo 560 I in Slave Mode 1 at 1/4000th of a second. But the power output decreases a lot after 1/1000th

    On-camera, manual non-TTL (Nikon Flash).

    my cheapo p-em2 do 1/320 no problem. even though the rated x-sync is 1/250. I can even go 1/400 with a little bit of clipping on top. You should try more than 1/500 and see how it fair.
