I regained wireless flash capability with the E-3…so I’ve been exploiting it recently. Luckily, Eneloops are rechargeable and I have enough batteries to go through several sessions.
Also, the E-3 is weathersealed, so even when it was sprinkling outside this morning, I managed some macro shots. Unfortunately, the FL-36R flash and the ZD 35/3.5 macro aren’t weathersealed…so I had to handle them with care.
I think the only downside with remote flash is not really knowing what the effect of the flash is going to be until after the shot is taken. I had to mount the flash on a tripod and have my son move it around until I got the light directed to where I wanted it to go.
