I have an EOS-M with a Meikon housing and I am trying to figure out the best way to trigger an external strobe. I got a 90EX speedlite, which works fine to trigger the strobe. It works with the camera's TTL to instruct the Sea & Sea strobe to output the correct power. HOWEVER, it has an annoying auto-off feature: whenever the camera turns off, the strobe shuts down as well.
I can enable the camera screen power down and disable the camera system auto-off, so the camera will stay on the whole dive. However, I would really like to be able to turn off the camera between dives, and not need to open the housing again to turn the 90EX back on.
I was wondering what my options are and if anyone has reccomendations. So far I have considered:
- Just open up the housing to turn the flash back on every dive. Works okay, but I'm worried about getting water into the housing when reopening it.
- Leave the camera on between dives. Potentially okay, but I battery barely lasts two dives as it is. Maybe I just need a fresh battery?
- Find another flash that doesn't auto power off. I've looked at some others, but they seem to also have power-save features that can't be disabled.
- Get a dedicated underwater strobe system. TRT-electronics makes one, but it's really expensive. For that price, I could get an EOS-M3 with a built in flash, and a new Meikon housing for it.
- Try to add a new bulkhead to the housing to use an electrical flash trigger
-
Either try to add a new button to the housing to turn the flash on, or solder something on to the flash button and link it to a new button on top of the camera power button so that the power button turns on/off both the camera and flash.
Any recommendations, or other, simpler options that I have overlooked?
