From zero to hero
Nikon D3100 (I saw it, it's very charming, I'd like one) set up, it will handle it easily, top pro image quality.
But the customer comes in and says: "no way, buster, that's a still camera, we need a professional video camera on this job."
So my mate thinks for half a sec and says: "not to worry, of course I only use this one for measuring the setup and such, and then I bring in the pro gear. So while the customer is out, he puts video rails under the Nikon, mounts it with a professional video lens hood, you know the huge ones with swinging gates and everything, and he puts a shoulder grip and a focus grip on also.
So the customer comes in, looks, and say: "hey, well done, I'm glad you brought in the professional video camera, go ahead".
Very impressive professional video camera, n'est pas?
