Samsung could be about to shake up phone cameras again. A report from Korean outlet The Elec says Samsung Electro-Mechanics is developing a telephoto module with continuous optical zoom — something no mainstream smartphone has offered yet.
Most current phones use fixed zoom levels, like 3x, 5x, or 10x, and then rely on digital zoom for everything in between. That’s why image quality tends to drop once you move off those set points. A continuous optical zoom would change that, letting the lens shift smoothly across a range while keeping detail sharp.
The way it works is pretty complex: the lens is split into multiple groups, with some parts moving independently to adjust focal length. The trade-off? A bulkier module, trickier mechanics, and the need for razor-sharp alignment. Samsung has already filed patents in 2024 and 2025, hinting it’s been working on this for a while.
What’s interesting is who might be bringing it first to the mainstream smartphone space. According to the report, Samsung is pitching the tech to Chinese brands like Xiaomi, which are usually quicker to adopt experimental features. For Samsung’s component business, it’s also a smart play in a slowing market — focus on high-value modules like continuous zoom, variable apertures, and thinner designs, and sell them to as many phone makers as possible.
While some phone makers lean heavily on image processing rather than optics — take Google’s Pixel 10 lineup, which uses AI to enhance zoom shots instead of adding bigger and better telephoto hardware — most Chinese smartphone makers still pack the best lenses they can fit in their flagships. That’s why Samsung’s work on continuous optical zoom feels like one to watch.
It’s worth noting this isn’t the first time we’ve seen seamless optical zoom in a phone. Sony’s Xperia 1 VII can move between 3.5x and 7.1x optically without much loss in detail. The problem? Xperia devices have never really clicked with mainstream buyers. They’re solid in some areas, but not well-rounded enough to compete with the big players in the space.
If Samsung’s development goes as expected, continuous optical zoom could finally make “super zoom” on smartphones more than just a marketing gimmick. But for now, it looks like Chinese flagships will get the first shot.
