Hi,
I am using a Sony A6000 in a Meikon Underwater Housing, with two Inon S-2000.
Strangely enough, even though the Switches are at S-TTL setting, there is no pre-flash and the flashes seem to fire at the same power regardless of camera settings. This can result in under- or overexposed pictures.
As far as I know, the magnets are only necessary for manual shooting.
Anyone got any ideas? I am thankful for any and all help.
