Those two lenses will not enable face detection AF within the EOS C100 Mark II. Technical design specifications are at the behest of Canon engineers and are not decided at the technical support level. We are however sorry for any inconvenience that this may cause you.
Lenses that support face detection AF:
- EF 24-105mm f/3.5-5.6 IS STM
- EF-S 55-250mm F4-5.6 IS STM
- EF-S 18-135mm F3.5-5.6 IS STM
- EF-S 18-55mm F3.5-5.6 IS STM
- EF-S 10-18mm F4.5-5.6 IS STM

We are not aware of third party lenses that are compatible with this feature as those are not tested by Canon.
Only the STM versions of these lenses are listed for compatibility with this feature.
