Vivo X300 Ultra’s 00mm and 400mm ZEISS telephoto extenders announced for extreme smartphone zoom
Vivo has revealed two new ZEISS telephoto extender lenses for the upcoming Vivo X300 Ultra, aimed at pushing smartphone photography further into long-range shooting. The 400mm teleconverter was earlier showcased at MWC 2026, and now the company’s product manager Han Boxiao has also confirmed details about a 200mm variant. These accessories are designed to significantly extend zoom capabilities while maintaining strong image clarity.
Vivo X300 Ultra to support 200mm and 400mm telephoto extender lenses

The first accessory is a 400mm telephoto extender G2 Ultra, which is designed for creators in mind. According to Boxiao, the lens delivers an equivalent 400mm focal length, which currently represents one of the highest magnification levels seen in smartphone add-on optics. When paired with Vivo X300 Ultra’s 200-megapixel periscope telephoto camera, the system can produce direct optical images at extremely long focal lengths. Using a 23mm equivalent focal length as the baseline 1x zoom, the setup effectively reaches about 17.4x pure optical zoom with the 200-megapixel sensor.
Vivo also claims that the telephoto camera now supports improved optical stabilization, including around 3° optical stabilization along with a new high-refresh tracking system capable of maintaining focus at up to 60fps. Even after attaching the extender lens, the setup reportedly maintains CIPA 4.5-level stabilisation. The company suggests that this allows users to capture usable shots even at focal lengths as extreme as 1600mm, making distant subjects such as wildlife or stage performances easier to photograph.
A lighter 200mm extender designed for portability

Alongside the larger accessory, Vivo has also introduced a redesigned second-generation 200mm extender lens G2. This version is intended to be lighter and easier to carry. The company states that its weight has been reduced by 27 percent, bringing it down to around 153 grams while also shrinking the overall size.
Despite the smaller body, the optical design has been upgraded. The lens now includes 15 elements instead of the earlier 13, which is expected to improve image clarity while maintaining strong stabilization rated at CIPA 6.5. Vivo says the compact design makes it practical for everyday shooting without compromising telephoto performance.
These accessories are part of Vivo’s broader ZEISS camera ecosystem built around multiple focal lengths. The system covers lenses ranging from ultra-wide 14mm to standard 35mm and portrait-friendly 85mm, along with the longer 200mm and 400mm options. The above image also shows a 2.35x ZEISS telephoto extender, which works with existing X300 models. Likely, it will also be supported by the X300 Ultra.
