Can a tv lens for 2/3" cover super16 format?
NO! A 2/3" lens is only for about a .4" image diagonal which is smaller
than a normal 16mm frame. Most 2/3" lenses, especially zooms, will give
vignetting in the corners of a normal 16mm frame, and will be grossly
inadequate for super-16.
A 1" video lens is for about a .6" diagonal, which will cover the
super-16 frame in most cases, I would think.
Confusion sets in because the 2/3 or 1" designation refers to the
overall diameter of the old glass vidicon tube, *not* to the actual size
of the image area. The terminology has been retained with modern CCD
pickup devices having equivalent sensitive areas, even though there is
nothing on the CCD that has a diameter.
