Earlier this year, a rumor suggested that the Huawei-Leica partnership is over and the photography brand is looking for other long-term partners. The first rumors pointed to Honor and Xiaomi, and it seems that at least half of them were correct.
According to Digital Chat Station on Weibo Leica has already entered into an agreement with Xiaomi, so the upcoming Xiaomi 12 Ultra will have Leica branding on its camera lenses. The smartphone is expected to arrive sometime in Q1 2022, a little later than the standard Xiaomi 12 series.
It is currently unclear what contributions Leica will make to the camera setup, but we can at least expect some color filter and input regarding the overall processing. We will update you when we hear more about it.
