Xiaomi 18 Ultra reportedly to keep continuous optical variable telephoto seen on 17 Ultra

What’s being reported

It has been reported that Xiaomi (小米) will carry the continuous optical variable telephoto module from the 17 Ultra into the upcoming 18 Ultra, keeping its no-digital-crop, multi-focal-length approach to portrait telephoto shots. The scoop, first surfaced on Chinese social platforms and relayed by ifeng, cites the 17 Ultra’s praised periscope setup — a 1/1.4‑inch large‑format sensor with a 3G+5P dual‑floating lens group — and says the 18 Ultra will further refine that assembly while reducing its overall volume.

Technical detail — why it matters

Reportedly the module supports continuous optical zoom from 75–100mm and covers four “golden” portrait focal lengths (75mm, 85mm, 90mm and 100mm) with no digital cropping, and outputs images at 200MP natively. Xiaomi previously described the design as unusually complex — three discrete lens groups handling base power, zooming and focus/optical compensation — and said components rose about 40% versus the prior generation even while the single‑lens unit replaces what used to require two lenses, allowing a 12% reduction in device thickness.

Context for Western readers

Optical engineering has become a key battleground in flagship phones worldwide, from Samsung and Apple to China’s Huawei and Xiaomi. Why the fuss? Telescopic periscope lenses promise real optical zoom at portrait distances without reliance on software interpolation — something consumers and reviewers prize. It has been reported that Xiaomi aims to trade off complexity for a slimmer chassis and more flexible focal lengths, but those claims originate from manufacturer‑adjacent leaks and platform reposts and should be treated with caution. Geopolitical factors such as supply‑chain restrictions and export controls have reshaped parts sourcing and competitive incentives in China’s smartphone industry, making in‑house optical innovation an attractive path for vendors seeking differentiation.
