The two companies aren't revealing specifics or launch dates for the first Zeiss-equipped phones in the HMD era.

However, it seems likely that HMD will bet on camera quality as a selling point as it moves to higher-end phones and expands sales to countries like the US. A rumored upcoming model, possibly called the Nokia 9, is believed to pack the dual rear cameras you see on many recent smartphones -- a Nokia brand photographer even posted a video that corroborated the leaks. While that specific device might not use Zeiss tech, HMD could clearly use the help as it steps up competition with camera-centric mobile rivals like Apple and Huawei.
