In Topic: Underwater settings for the Olympus OM-D E-M5

26 November 2012 - 08:01 AM

Great to see folk interested in this cool camera :-) An excellent bit of work, I'd add a couple of thoughts on the flash section...


Flash:
Shooting Menu 2
RC Mode -> Off, unless you have a compatible RC capable Olympus UFL-2 or housed Metz/Olympus land flash.
RC Mode works only with RC mode flashes and sends control signals via flash pulses to control the relative outputs of external strobe channels. Unless you are using an RC flash underwater it won't work meaningfully! Using RC flashes you can run upto 1/8000th - but that's not useful very often!

Weirdly I found turning on UW Mode (so the clip on flash will fire in the Oly housing in my case) appeared to limit sync speed to 1/160 of a second (from the selected 1/250th) for slave or S-TTL mastering - maybe I had another interlocked setting engaged or had an old firmware version. Not an issue for Nauticam guys :-)
