Yes, the other shot is at 400ISO, but it is shot at f/4.0 whereas the Oly is at 200ISO f/2.8, so there is no disadvantage here. Also, shutter speed has no impact on flash exposure, as the room was quite dark. I used high shutter speed to avoid influence from ambient light.

Yes, I should have used the same settings on both camera for the first pic, but I did not notice. However, all the other pics use similar settings and get the same results.

Regarding focal length, remember we are talking aps-c vs µ4/3. On the OMD, I am using the Panasonic 14 2.5, while I use a zoom lens on the Canon. I tried to approximate the same focal length.

Ok just tried with my 14mm on my OMD and yes at 1/160 sec you going to have problems.

Just tried it myself, identical result, under exposer.

This is to be expected and its not a fault of the system or flash, its like I said earlier.

"Could be part of the problem.

50D Guide number of 13m @ ISO 100
OMD Guide number of 10m @ ISO 200"

Go into the cogs menu and select custom flash and reduce the slow limit, try 1/30th and look at the difference.

This plug on flash is really designed just for the odd bit of fill or use as a commander nothing else.
