IV. Description:
SmallRig 2× Magnification Telephoto Lens for Phones (T-Mount) 5920 is engineered specifically for smartphone telephoto lenses (4x & 5x), providing superior optical zoom for clearer, more distant shots. The kit includes a teleconverter, a cleaning cloth, an ultra-wide lens sticker, and a storage bag. The 2× teleconverter doubles the optical magnification of your smartphone's telephoto lens, with a minimum focusing distance of 5m (16.4ft). Crafted with multi-coated optical glass, these lenses minimize distortion and color shift, delivering vibrant, full-color HD output. Designed for T-mount phone cases or lens clip, the lens comes with an included sticker to cover the ultra-wide lens, preventing camera interference and vignetting for optimal performance.

V. Precautions:
① This kit is designed exclusively for telephoto lenses. Do not use it with the main or ultra-wide camera. Ensure your phone is set to the 5× telephoto or 4×/8× telephoto setting for optimal performance with the teleconverter. ② When using the Phone's native camera app, ensure Macro Mode (14mm lens) is turned off. And apply the provided ultra-wide lens sticker to prevent the ultra-wide camera from activating, which causes severe vignetting. ③ For the 2x telephoto lens, the minimum focus distance is 5m. If the subject is closer than 5m, the main camera will engage instead, resulting in heavy vignetting in the frame. ④ For optimal results, use third-party apps(e.g., Lightroom, Blackmagic, ProCam, Indigo, Fotorgear). to manually activate/lock the telephoto lens. ⑤ Align the lens precisely with the phone's camera to avoid vignetting. Depending on your phone's telephoto magnification, slight digital zoom may be needed to eliminate any remaining vignetting. ⑥ A tripod or stabilizer is recommended to prevent motion blur.
