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.
