OM-D E-M5 underwater review
Thanks, interesting. I'd very much like to use the OM-D underwater, but I am talking inches, not tens of meters, so I feel the full housing is going too far, and I don't really trust the bags.
Glad you liked the camera - I passed on the D4/D800 option myself and went D3 to OM-D, very happy.
I haven't yet played with the flash system on that camera - still organising new kit, but I don't remember any significant TTL delay on Oly's flash system, and hence wonder if you had something set incorrectly.
