Thanks for your replies.
I only noticed this smell when trying to test the slave part of the flash. I used the onboard flash to trigger the vivitar's slave. Each time the k-x's flash went off to try to get a auto focus (it was dark), the vivitar's flash went off consecutively. After, I noticed this smell when handling the flash. Also the built in diffuser was over the flash head.
I tried again this morning with a full flash (w/o the diffuser) and you have to put your nose directly over the flash head to smell anything odd.
Nonetheless I called Vivitar customer service and they said I should send it back. They said it would take about 3 to 4 business weeks to send me a new one.
This is unacceptable to me !
They must have been form a foreign country as their English was hard to understand. I thought that they said that would send me a new one first, and I should then send the other back. But I presume that they would want this one first.
I am going to wait this one out as I've read that others have the same type of thing with their flashes, and in this case, you don't notice it at all in regular shooting, unless you take a whiff of flash head after the shot! Also the smell is more of an "electronical plasticy" burning type of smell but only a faint smell. It could jsut be that it comes from heating of their cheap plastic.
Thanks again!
Jake
