Our G-Series Lenses are primarily designed to work best with the main camera of the iPhone, known as the Wide Angle camera (W).
Regarding the Telephoto 2x lens, this is not fully compatible with the Telephoto camera of the iPhone 15 Pro/Pro Max and 14 Pro/Pro Max due to the specifications of the newer 48MP camera sensors.
While it may be possible to use the Telephoto 2x lens with the Telephoto camera, we do not recommend it as it is not optimized for such use.
Previous generation iPhones, such as the iPhone 13 Pro/Pro Max and earlier, may have higher compatibility due to the lower dimensions and specifications of their 12MP camera sensors.
If you choose to use the Telephoto 2x lens with the Telephoto camera, please note that the focus may not be optimal. However, you can adjust the manual focus using our REEFLEX Pro Camera app by setting it to MF = 1 for infinite focus.
