I have a canon EOS Digital Rebel XT and I recently bought a studio lighting kit,

consisting of 3 Lumisoft flashes.

Lumisoft FX150:

- Power 150Ws

- Model Light 50W

- Charge time 0,5-3s

- Flash Duration 1/800

- Fuse Capacity 5A

The problem is that they don't work when I fire with my Cullman external flash

mounted on camera. The fire, and the flash fires also, but the image I get is

totally black.

The otehr issue is that although they work perfectly fine with sync cable

connected to sync gate on camera, I sometimes feel some discharge when touching

the camera after the flashes have fired. Why could this be and what do I do?

I do not want my camera or the flashes to take any damage... :(

thank you
