sirui anamorphic lenses cannot be used with all smartphone models, but they are compatible with a wide range of them.
Many sirui anamorphic lenses are designed to be universal, with features like 17 mm screw threads or universal clips that allow them to be attached to most modern smartphones. For example, the Ulanzi 1.33XT and 1.55XT sirui anamorphic lenses are compatible with popular brands such as iPhone, Pixel, Samsung Galaxy, Xiaomi, HTC, Nokia, LG, Motorola, and OnePlus. The Beastgrip Pro + 1.33X sirui anamorphic Lens MK2 Bundle also claims to be compatible with all iPhone and Android phones.
However, there are some limitations. Some sirui anamorphic lenses, like the Moment sirui anamorphic Mobile Lens, require specific cases (such as the Moment M-Series or T-Series cases) to be used, which means they may not be compatible with all smartphone models or cases. Additionally, older or less - common smartphone models may not have the necessary camera specifications or physical dimensions to work well with sirui anamorphic lenses.
