No comment on the video as I have not watched it.
What surprises me is Canon has again released a brand new XD series without a headphone jack.
The 1D X does not have one and now this latest model from Canon does not have one.
Not all of us want to use external recorders to monitor sound levels during a recording.
I don't get what surprises you so much.
For all intents and purposes this camera is nothing more than the 5D2 put into a slightly cheaper body and added a few extra bells and whistles (in the Wifi).
If you want to record sound in video then by all means thats your prerogative but all that in camera sound is really good for is a scratch track if filming shorts or as a talking heads mic if shooting BTS or doco style.
External sound will ALWAYS be a better option.
People that want to shoot video on a DSLR forget that its not a video camera and need to realise that it costs money to start playing with the big kids.
Sure you can buy a 650D or 6D for between $800 and $3k but then what?
Are you going to stick your Sigma 50mm f1.8 on there or are you also going to invest in decent lenses?
A set of CP.2s are not cheap.
Are you going to use crappy in camera sound or are you going to invest in a H4n or Tascam recorder, or better still hire an actual sound recordist and use something like a Sound Devices 744T?
Its one of the things that separates the professionals from the hobbyists.
