In the past two years, mobile phone image configuration has experienced multiple inversions. The controversy about the periscopic telephoto lens has not fallen. Some people think this is very practical. They usually use the scenery in the distance and the courseware for the meetings of the patronize meetings. Some people think it is a gimmick. Who can drive a hundred-fold zoom all day to shoot the moon? And if you get too far, the image quality is very blurry when you shoot the digital zoom.

It is undeniable that many manufacturers regard the high-power zoom achieved by periscope telephoto lenses as a selling point, and 100x and 120x zooms must be marked in the eye-catching promotional copy. At the same time, some manufacturers insist on not using periscope telephoto lenses, but instead exert their efforts on ultra-wide-angle lenses. Are the periscope telephoto lenses on mobile phones practical?

bottom is too small, and the image quality is limited.

First, let’s talk about the image quality issue. The periscope telephoto lenses used on mobile phones are generally pitifully small in size. Larger sensors like the periscope telephoto on Xiaomi 12S Ultra are IMX586, with an /2-inch bottom area, which is different from the 1/1.56-inch common main cameras, not to mention those 1-inch large-sole main cameras. And the aperture is pitifully small.

other periscopic telephotos, not to mention, each base is smaller than the other, mainly due to the size of the module. The periscopic structure needs to stand up the sensor. If the base is larger, it can be imagined that the thickness of the phone will be very touching.

sensor bottom area directly feels the upper limit of image quality. In addition, the telephoto image will also be affected by air particles, which requires very high requirements for the lens module. Therefore, it is very touching to see the ultra-telephoto lens on the camera, because the telephoto lens with a large aperture requires a complex mirror group, and in the limited space of the mobile phone, the quality of the mirror group is naturally not much better. also destined that the image quality of the periscope telephoto lens can only be of sufficient viewing level.

can be taken, which is more important than taking better

Since the lens group design is complicated and the picture quality is not good, is the periscope telephoto lens on the mobile phone really unnecessary? The answer is no. In our daily life, it is more important to take pictures than to take pictures better.

Go to the concert, you only get the tickets in the last row. If you want to shoot the lead singer clearly, the periscope telephoto lens will come in handy.

At home, I heard someone quarrel outside and wanted to eat melons. The periscope telephoto lens takes you to eat melons at close range.

Go to the zoo to see the monkey tiger, take a close-up of the tiger's eyes, and the periscope telephoto lens is very effective. For more specific scenes, periscope telephoto lenses are still very useful.

Finally, it should be pointed out that periscope telephoto lenses are suitable for function configurations. It is a bit too much to take them out of the way to promote them as selling points.
