Bandito Brothers, known for its groundbreaking work with DSLR video cameras, shot the above BMW commercial spot using the likes of the Canon 5D Mark II and Nikon D3s. You can get a peek into the behind the scenes action that went into making the commercial spot (which includes a BMW with no doors and gaggle of DSLRs mounted all over the inside at out) at BMW Blog.
Bandito Brothers is familiar with the BMW and DSLR combos though. The following video was also shot last year with the 5D Mark II.
You can find a full description of what went into the second film over at Planet 5D.
