Lenses

Filmmaker IQ has posted a couple of videos on lenses. The first is on the properties of camera lenses; the second is on depth of field and equivalents.

With a grounding in science and history, we now dive into the properties of camera lenses and explain the features of the modern camera lens for photography and cinematography from, Focal Length, Aperture, Primes vs. Zooms as well as some specialty features.

How much space in front of the lens will be in focus? That question defines Depth of Field – but this simple concept has lead to a staggering amount of confusion in today’s multi-format camera environment. Through some fundamental scientific demonstrations, we will clarify concepts like circle of confusion and lens equivalency.

But wait, there’s more. A bonus video on the Science of Camera Sensors.

A lot goes on under the hood when you press “REC” – check out the fascinating science behind film and electronic camera sensors.
