Phones with ZEISS Master Lenses Collection

A photography brand's name on a phone camera marks a partnership over the optical design and the image processing: the lens formula, the coatings, the colour science and the contrast curve are tuned to that brand's signature. The brand does not physically manufacture the sensor or the lens; the partnership is mostly about tuning and approval.

ZEISS is the German optics company founded in 1846, working from microscopes to space optics. Its most visible contribution on the phone side is the T* coating that suppresses reflection and flare — it reduces the halos that form around light sources in night shots.

The "Master Lens" name describes a set of profiles the maker puts in the camera menu that imitate the image character of classic photographic lenses: the framing of a given focal length, that lens's bokeh shape and edge fall-off are built in software. It is not a physical lens change but a computed choice of look.
