Is anyone using the Neewer EXT14 ringflash with the Sony R10m4 ?
I have this flash for my main camera a Canon 5d4, but decided to try it on the m4 in manual flash mode on the ringflash.
I get decent photos most of the time, any tweaks to exposure are quite simple - BUT the one issue I have is that if I have the ISO at anything other than Auto or over 4000, after the initial half shutter push to get focus, almost immediately both back screen or looking through the viewfinder goes almost black and I cannot see the item being photographed
Is there anyway around this as there are occasions I would like to use the ringflash with the m4 but being restricted in what I can view at the time of capturing is not really convenient.
Andrew, I don't have access to my RX10M4 or the manual at the moment to check it out, but I found this on the net that should help you.
