A New Level of Mobile Imaging: The Rise of Telescopic Telephoto Lenses
The continuous upgrading of mobile phone camera function has promoted the innovation of mobile phone imaging technology. In this process, the emergence of telescopic telephoto lenses is undoubtedly an important milestone. As a new optical zoom solution, it is expected to bring an unprecedented qualitative leap to mobile phone telephoto photography.
The telescopic telephoto lens design of Huawei's P70 series mobile phones is the latest embodiment of this innovative technology in the field of mobile phones. The series is equipped with a periscope lens that achieves up to 4x optical zoom capability. Compared with traditional fixed focal length lenses, this retractable telephoto lens design allows the Huawei P70 series to have more flexibility and shooting capabilities when taking telephoto photos. Whether you're shooting distant landscapes or capturing moving footage, you can get sharper, more detailed photos.
This design of the Huawei P70 series is not completely innovative. Back in 2012, Samsung had adopted a similar 21x optical zoom telephoto lens on the Galaxy Camera. The camera's lens can be scaled from a 23mm wide angle all the way up to a 483mm telephoto, giving the user an extremely wide range of viewing angles. Although the Galaxy Camera focuses on camera functions, its telescopic telephoto lens design undoubtedly pointed out the direction for the later development of mobile phone imaging technology.
A year later, Samsung took the Galaxy S4 2013 as a step further in the field of mobile photography. The Galaxy S4 is equipped with a "zoom ring" feature that allows users to shoot infinitely by swiping with gestures, achieving an effect similar to that of a telescopic telephoto lens. While this design didn't really enable retractable zoom at the optical level, it laid the groundwork for later hardware upgrades.
Apple's iPhone has always taken a different technical route when it comes to telephoto photography. For many years, the iPhone has used multi-lens combination and digital zoom technology to achieve telephoto camera function, and has never tried to use a telescopic telephoto lens design. This is related to Apple's consistent design philosophy, which pursues a slimmer body design, while telescopic telephoto lenses require a certain amount of lens protrusion.
There's no denying that the combination of digital zoom and multiple lenses can really improve telephoto capabilities to some extent. However, compared to optical zoom, they still lag behind in image quality, detail preservation and zoom capabilities. The telescopic telephoto lens design will undoubtedly bring a new experience to the mobile phone's telephoto photography.
It is not easy to design a high-quality telephoto lens in the limited space of the mobile phone body. This not only requires solving the problem of spatial layout of the lens module, but also requires in-depth optimization in optical design and lens material selection to ensure the quality of photography. It is understood that the periscope telephoto lens of the Huawei P70 series has been exclusively polished and optimized, in order to have excellent performance in zoom performance and image quality details.
In addition to Huawei and Samsung, other mobile phone manufacturers such as Xiaomi and OPPO are also actively deploying telephoto lens technology. We can foresee that this technology will be more widely used and developed in the field of mobile phone imaging. With the increasing demand for focal length for mobile phone photography, telescopic telephoto lens will surely become the mainstream solution for mobile phone telephoto.
The advent of telescopic telephoto lenses marks another leap forward in mobile phone imaging technology. It will not only bring users a better telephoto experience, but also promote the further upgrade of the entire mobile phone imaging hardware and algorithms. In this process, Samsung can be said to be the pioneer and pioneer of this technology, and the Huawei P70 series is the latest representative of its successful application in the field of mobile phones. We have reason to believe that with the continuous emergence of more innovative designs and technologies, the ceiling of mobile phone imaging will be broken again and again, bringing users an unprecedented imaging experience.
