Hi Darren, Is that for real or a clever camera trick?
If you have smoke from your camera it means that something is being burnt for it to be produced. May be a known but safe thing (possibly grease vapourising) but I would look into it as my experience in electronics tells me that when you get smoke things are getting stressed and failure could be soon.
I hope its nothing in the end though would be a bummer to have such nice kit go down on you.
