I'm using a nikon 1 aw1 with the 11-27mm lens and setting the built in flash to manual 1/32 power to optically slave a sb105 for off camera flash . I'm after a budget second slave flash , sb105 strobes are about $250 , are
there any newer quality options around the same price I should consider or my other thought is to dry bag a cheap land flash .
My other thought is to increase the stock depth limit on the aw1 of 15 metres by also dry bagging it - if the bag does leak slightly the water should only slosh around harmlessly . A catostrophic flood would be a different matter . Any thoughts ?
