"RE: Olyumpus Flash on D5000?"

Welcome to Nikonians,

First, the voltage provided by the flash unit to the hot shoe can vary from 12 VDC or less to over 200 VDC. The digital cameras using solid state circuitry are designed to work with much lower voltages than the old film cameras that used mechanical switches. And that is why Nikon prints the following in all dSLR manuals:

>Use Only Nikon Flash Accessories

> Use only Nikon Speedlights. Negative voltages or voltages over 250V applied to the accessory shoe
could not only prevent normal operation, but damage the sync circuitry of the camera or flash. Before
using a Nikon Speedlight not listed in this section, contact a Nikon-authorized service representative
for more information.

You can check the flash voltages at Photo Strobe Trigger Voltages. If you need to you can buy a safe syncy voltage isolator like Safe Synch.

And as with any non-CLS flash, you will need to use the "Manual" flash mode and copute your aperture based on you flashes GN, Guide Number,

For paid memberships there is more help is available in the Speedlight and Lighting forum.
