SmallRig 5920 2× Magnification Telephoto Lens for Phones (T-Mount)

SmallRig 5920 2× Magnification Telephoto Lens for Phones – Doubles Optical Zoom for Smartphone Telephoto Lenses

The SmallRig 5920 is a 2× teleconverter designed specifically to double the optical magnification of compatible smartphone telephoto lenses. It pairs with a phone's existing telephoto lens to reach clearer, more distant shots while maintaining HD color fidelity through multi-coated optical glass. The kit ships with accessories to protect and store the lens and to prevent interference from the phone’s ultra-wide lens.

Key features

• The 2× teleconverter doubles the optical magnification of your smartphone’s telephoto lens.
• Minimum focusing distance: 5 m when used with the telephoto lens.
• Multi-coated optical glass reduces distortion and color shift, producing vibrant, full-color HD output.
• Designed for use with T-mount phone cases or lens clips.
• Includes a sticker to cover the phone’s ultra-wide lens to prevent camera interference and vignetting.

Usage notes and recommendations

• Only use this teleconverter with telephoto lenses. Do not attach it to the phone’s main or ultra-wide cameras.
• Set your phone to the telephoto mode required for best results (for example, 5× or the phone’s 4×/8× telephoto setting) before attaching the teleconverter.
• If the subject is closer than 5 m, the phone’s main camera may activate instead, which can produce heavy vignetting in the frame.
• For reliable telephoto selection and lens control, use third-party camera apps such as Lightroom, Blackmagic, ProCam, Indigo, or Fotorgear to manually activate or lock the telephoto lens.
• Align the teleconverter precisely over the phone’s telephoto camera to avoid vignetting. Depending on your phone’s native telephoto magnification, a slight amount of digital zoom may still be needed to remove any remaining vignetting.
• Use a tripod or stabilizer to minimize motion blur when shooting at long focal lengths.

Compatibility

• Compatible with: iPhone 15 Pro Max, iPhone 16 Pro, iPhone 16 Pro Max (5× telephoto), iPhone 17 Pro, iPhone 17 Pro Max (4× / 8× telephoto).

FAQ

Question: Can I use this teleconverter on my phone’s main camera or ultra-wide camera?

Question: How can I avoid vignetting when using the teleconverter?
Answer: Align the teleconverter precisely over the phone’s telephoto camera and, if necessary, apply a slight digital zoom depending on your phone’s telephoto magnification. Also use the included ultra-wide lens sticker to block the ultra-wide camera and prevent interference.

Question: Which apps should I use to ensure the phone uses the telephoto lens?
Answer: For optimal control, use third-party camera apps such as Lightroom, Blackmagic, ProCam, Indigo, or Fotorgear to manually select or lock the telephoto lens before shooting.
