Equivalency is one of those topics that not only confuses a lot of people but also turns into some pretty heated arguments. It’s why people think that a lens of one focal length “turns” into another when you put it on a camera with a differently sized sensor. It’s why your depth of field both does and doesn’t change at the same time.
The video above was made as a follow-up to a video recently published by The Slanted Lens to ask does size really matter?. Naturally, when comparing medium format, full-frame, APS-C and Micro Four Thirds cameras, each with their own unique sensor sizes, it raises a lot of questions. And it did. So, this video is designed to answer them.
