IndieWire lists the cameras used by filmmakers at the 2013 Tribeca Festival. The ARRI Alexa is, unsurprisingly, a popular choice, as is the Canon 5D.
But what I find heartening is just how many different types of rigs are in use, from SLRs to older videocams to iPhones. There’s no one “right” camera, so fetishizing pixels and dynamic range is often detrimental.
If you’re making a movie, the best camera is the one that works for your style, story and budget.
