Nokia 7 is the only second Nokia Android smartphone to come with a Zeiss-branded rear camera after Nokia 8. It also is the only second camera to support Bothie or Dual-Sight feature.
Now if a claimed reply from HMD support has to be taken into account, it seems Nokia 7 is using Samsung Camera modules in both front rear and front cameras. The rear camera has Samsung 2P7 camera module while the front camera has Samsung 4E8 camera module as per the reply provided by HMD support.
This is however not surprising as Zeiss branded optics were always mated with camera modules created by other companies in some legendary Nokia Cameras. For example, the 41MP camera modules for Nokia 808 PV and Lumia 1020 were created by Toshiba in collaboration with Nokia.
