Lenses for Filmmaking

In this filmmaking class, Karl explains the various types of lens you can use when shooting video.

He looks at traditional cine lenses and compares them to modern stills lenses, many of which can now be used for moving images. He also explains the difference between spherical and anamorphic lenses, as well as the difference between T-stops and F-stops.

Covering manual aperture adjustments, auto-focus and image-stabilisation capabilities, this comprehensive introduction will give you a solid understanding of lenses for filmmaking.

  1. I am confused about the point on focusing: you mentioned with cine lenses a guy does the focusing “by wire” or “on a monitor” but then you showed immediately that these lenses have no electronics. So how can the focusing guy do the focusing especially on another monitor? Thanks in advance for explaining.

    1. Hi, a reference monitor is connected to the camera via HDMI or SDI and the ‘focus puller’ can view that monitor to check and adjust focus.
