Zeiss Distagon 8/2 for 16mm format, or Red One 2K. Bought this as a wide angle for those 120fps shots... Should also work well on the Scarlet cinema. (Or A-cam dII... or other 2/3" cams with PL mount)
In very good condition, no blemishes on the glass, used only a couple of times.
PL adapter by Les Bosher included.
