It is within the capabilities of the camera, there is nothing false about it.
The season finally of House season 5 was done on Canon 5D2.
Anthony Bourdane's "No Reservations" is shot on Canon 7D.
Nissan DId a advertisement recently with Canon DSLR.
If you want to do video, nothing wrong with a DSLR. Even cheap lenses are very capable.
I’m working in broadcast-television industry for last twenty (or so) years.
It used to be huge difference between pro and consumer cameras and editing equipment. But not anymore.
The only huge difference between Tli and normal video camera would be in auto focusing. But for some shots it is not so important and some pro would use manual focus anyway.
Even kit lens would have same optical quality as lens on pro video camera and the recorded video signal would be the good for editing. Audio is different, but not for commercials production, which needs to be recorded to separate thing in separate place anyway.
Of course nobody is going to edit anything more less important on crappy Microsoft software. They can’t even make their browser working properly. Where are industry standard software solutions available for last ten+ years. Avid software is not so expensive anymore. FinalCut Pro is affordable and many pro using it for production these days. Not to mention After Effects which exists since 1993 and very affordable.
Studio Lights? You need them even for family portraits if you want good picture.
And renting of small studio with lights and backgroud costs as low as 100 USD per day.
