I've been reading that Olympus OMD EM5 only works with Yongnuo RF602 but not 603 although there is a hack to it but i wont go into that. i dont want to hack my stuffs. i want to buy it and pray that it works. pay and pray. thats how i roll. thats just the way it is. i dont want to open up my trigger and solder this solder that. no. just too much hassle.
EM10 being almost similar to EM5, i worry the same issue with RF603 would resurface. I just purchased a set of RF603 before i bought the OMD although the ones i bought are the latest from Yongnuo, the RF603CII, i guess its a version 2 or Mark 2 they say. Anyway, its still model 603 but good news it works!! so if you want a cheap wireless triggers for your OMD, get the new RF603CII.
Some test shots below...
shot with OMD EM10 with RF603CII to trigger the flash. Flash is Yongnuo 560III
i just bought a pair of Yongnuo's flashes, the YN560III, as it has a built in wireless so you dont need to buy a receiver for it. Just get the RF603CII and set it to the same channel and viola, you got some strobing/strobist project to do!! This flash is cheap too.. i got it for USD$136 for 2 flash.
i set both flash to the same channel and triggered wirelessly by OMD EM10 using the new RF603CII
All i can say is its...
