My D5000 manual states "Use only Nikon flash units. Negative voltages or voltages over 250V applied to the accessory shoe could ....damage the sync circuitry of the camera..." Obviously Nikon wants to sell their own equipment. I have a handle mount Vivatar 365 flash I have used for years on my old film camera, and would like to use it, in manual mode, on my D5000, but obviously, I do not want to damage my D5000. Does anyone know definitively if using this Vivatar 365 will or will not damage my D5000
Nikon might want to sell their product, but they also do not want the purchasers to unnecessarily damage their equipment. From the number of 3rd party RF remote manufactures and lens manufacturers one might conclude that Nikon does not discourage 3rd party products. But Nikon does have a quality edge in what it sells, so the purchase option is up to the user. There are 2 companies that are marketing RF modules to convert the Nikon CLS Wireless control to RF so the control distance and interference issues have been greatly improved for the photographer.
When using a Nikon F and a Vivitar 285 on a hot shoe mount I received quite a jolt through the PC sync port.

I have an old Vivitar 365 that I haven't used in years. The thing drank "C" batteries like there was no tommorrow. According to : http://www.botzilla.com/photo/strobeVolts.html the sync voltage is 46V. Much higher than I would trust to use with a DSLR. The Wein Safe-Sync is a good idea. Better Safe than sorry.
Another thing to consider is that flash control has come a long way since the Auto flash mode of a Vivitar 365. Nikon i-TTL flash control and CLS is like Magic compared to the old days. Good Luck and Enjoy your Nikons!
