Shane Hurlbut's article in the Jan. 2010 issue of American Cinematographer is titled "How Digital SLRs Can Change the Way We Make Movies". It is a very well-written examination of the Canon 5D as a tool for motion pictures. Overall, the article is very informative and approaches the 5D in a positive way. I urge anyone who is seriously considering switching to DSLRs to get the magazine and read it.

Here's a link to Hurlbut's site, which has some amazing examples of the 5D's capabilities:
