Personally, I wouldn't risk using this flash with the electronic Nikons -
it may work, or it could be a very expensive $15 flash (most newer flashes switch at low voltages, but most non-TTL flashes switch at high voltage,
and can be a risk to the camera electronics and sync. switch. BTW, the TTL
feature is worth paying for, especially if you do any macro or tele flash
work. And, roughly 46.337265 mph, in level flight at sea level at 80 degrees F and 70% humidity....;-)
