Ikelite D70 housing
According to Ikelite, not all of the hotshoe pins are connected to the bulkhead on the D70 housing. This will make it impossible to use this housing with a housed SB-800 in wired mode re-wiring the housing. The required modification would cause the system to become incompatible with Ikelite (and other) strobes unless an additional, independent bulkhead was installed. Connecting the wrong strobe to such a bulkhead could conceivably damage the camera.
There also seems to be a difference of opinion on whether the pop-up flash will fire in the housing (to trigger an SB-800 in remote-commander mode). If anyone has the D70 housing, it would be very helpful to know whether the pop-up strobe fires inside of the housing (it needs to be popped before the housing is closed). An SB-800 isn't needed to test this, I just need to know if the popup fires.
Thanks!
