The PGYTECH Retrova 2× telephoto lens is designed for iPhone 17 Pro users who want to capture more distant subjects without sacrificing the convenience of mobile photography. The optical teleconverter provides 2.35× magnification and, combined with the iPhone 17 Pro cameras, achieves a 235 mm focal length equivalent, corresponding to 9.7× optical zoom. The range can be further extended to an equivalent of 960 mm and 40× magnification.
The advanced optical design with 13 elements in 3 groups and high-quality optical glass helps preserve a clear image, sharpness, and detail at high magnification. The lens is optimized for use with the iPhone camera's F2.8 aperture, making it suitable for photographing birds, performances, street scenes, city panoramas, and architecture.
The Retrova system is designed with future generations of devices in mind. When switching to a compatible newer smartphone, according to the manufacturer, only the case for the specific model should need to be replaced, while the other Retrova accessories can continue to be used.
