The CP2 is a step above the (video) DigiPrime series,and is targeted at Super 16 and DSLR/EVIL HD video, i.e. student and independent level cinematography. The Summilux-C line is in quite another class, PL mount and competes with the Zeiss Master/Ultra line, which are no cheaper.
Not to be pedantic but digiprimes are a very different beast, designed for 2/3" chips and much more expensive and built to higher tolerances than CP2s, CP2s are effectively cinevised zeiss ZFs. A set of CP2s would really not suit super16.
