Smartphone manufacturers have long been working to improve the photo experience. In order to make up for the shortcomings of ordinary lenses in long-range shooting, periscope telephoto lenses came into being. The innovation of this lens uses a fully reflective optical engine based on the principle of refraction, which allows it to achieve farther focus in a small space, breaking through the design limitations of mobile phones, achieving higher resolution and better detail performance, and gradually becoming the preferred configuration of high-end flagship mobile phone cameras.
For example, Xiaomi, OPPO, etc., have not only launched a variety of mobile phones equipped with periscope telephoto lenses, but also continuously optimized and adjusted in the actual application process. They increased the number and focal length of periscope lenses to suit the needs of different users, such as life, portrait and macro photography. Whether it's zooming in on the core function of a telephoto lens to "shoot the moon", or turning to portraits** or even using it as a macro lens, manufacturers are trying to open up new possibilities based on existing technologies.
In addition, it is understood that although the periscope telephoto lens has been developed in the field of smartphones, there are still some differences with the lens used in the Apple iPhone 15 Pro Max. The periscope telephoto lens of the latter is more compact, and its built-in monolithic prism can be reflected four times for better imaging. In contrast, the Android lens, on the other hand, tends to position the sensor vertically to minimize the impact of sensor size limitations, thereby improving image stabilization and focusing accuracy. This change not only significantly improves the stabilization performance, but also brings new expectations to people.
The R&D trend of periscope telephoto lenses undoubtedly reflects the pursuit of high-quality mobile phone camera performance in today's market. In an increasingly competitive market, even a small gap can determine the ultimate fate of a product. It can be said that periscope telephoto lens has become one of the important directions of optical innovation in the future, and it will also lead consumers to a new understanding of photography.
