...showing off how far you can push the thing till it breaks is kinda what you'd want..
For me it's not. It's a marketing video, as you stated, so they should try to give the BEST impression possible and not some 'guess what ISO this is and how good it might look if shot properly' thing. They can do that as well, but not for a first impression.
It's like serving you a raw piece of meat and saying 'just imagine how delicious it would be if grilled and served with vegetables and baked potatoes'.
I'm not blaming the guy, he's a photographer after all, I don't understand the marketing guys. This is a about video. Any of us know that using a DSLR for video is different than taking stills with it.
This is just my feeling, I've watched the short and just wasn't convinced. But I strongly feel that it would have been possible to do so, it just makes me mad.
