High speed flash synch with the D70

..... Chris has reported that's not the case with his YS90DX. ....

I am using a D70 in a Nexus housing with a YS90DX and I have the same problem as Alex notes - as soon as I turn the strobe on the camera will not set a shutter speed above 500.

It must be a hot shoe connector pin situation.....I bet you could cover some of the pins with tape and make it work....similar to the Ikelite 2 pin connector configuration.....just figure out which pins to cover

The two pins you need to fire the strobe are the one in the middle - the trigger - and the edge of the hotshoe - the earth. Alex

For the last couple of saturdays I've been practicing wide angle with my brand new D70/Ike housing/Sigma 15mm FE lens. I've been pretty impressed with some of the sunball/sunburst shots on this thread so I thought I'd have a go. I was at about 9 metres at the time. Settings for the shot were 1/1000th and f/13.

Admittedly, this was only on a shore dive in the southern suburbs of Sydney, so the water clarity isn't fantastic at about 8m. Still, I'm encouraged by the results. I think if I try again in shallower water and close down the aperture even further I should be able to get some nice 'fingers of light' around the sea dragon. I had previously tried this shot with my C-5050 and got pretty ordinary results.

Stunning shot Brook, what strobe and at what power did you use?

Also, how big is this Sea Dragon?

I have a single YS90DX. I think I shot it near to full power.

The sea dragon was about 10 inches long. I suppose he must have only been about 8-10 inches from the dome port at the time.

On my previous attempt at this shot I had used spot focus and was unable to get focus on the subject. This time I experimented with two approaches.

1. Use the 'Closest Subject' focus setting.

2. Focus on a rock from about 8" and then flick over to manual focus and shoot the sea dragon by estimating subject distance. This works due to the large DOF of the 15mm.

Both approaches worked well. This particular picture was taken using second approach.

FWIW. Shot in my kitchen sink with D70 at 1/8000, a 60mm micro Nikkor with a 2x teleconverter, SB80 on full power and the 2 back flash contacts taped over with Cellotape.[/img]
