Steve Yedlin on ‘Large Format’ Optics

http://www.yedlin.net/191106.html

But, in trying to describe “the big format look,” people often make a word-salad of focal length, AoV, and compression, like “you can get closer on a longer lens with the same AoV but it’s more compressed.” But that’s just a self-contradictory jumble of words that doesn’t really have any meaning. AoV and perspective are each properties that are not unique to one format size as opposed to another and are independent of one another (putting a certain lens on a camera doesn’t force you to put that camera in a certain position in space — a filmmaker is free to choose AoV and camera placement separately).
