Just thought I would point out a video shot with a 5D MKii Ashcon found today. There was a video put up on youtube a week or two back, but that one was obviously done with a boatload of money. This video is supposedly shot by a guy (albeit with awesome gear) wandering around Tokyo for three days, then edited by someone else in two days.
A high-budget video (also shot with a 5D MKII) can be seen here.
