Cine lenses for the movie industry are made with high demands in both resolution, and optomechanical performance. Still camera lenses could afford inexpensive zooms whereas the zooming, and focusing mechanism for cine cameras have to be wobble free because they are performed during shooting.
Many camera manufacturers are going up full size format (24 x 36 mm) in their cameras. Older cinema lenses that only covered the Super 35 format are at stake.
