2×, 3×, 5×, 10×, and the multiples of the telephoto of mobile phones are used differently.

2×, 3×, 5×, 10×, and the use of telephoto multiples of mobile phones is different as follows:

Double, triple, fivefold and tenfold telephoto lenses can be seen in mobile phones of major manufacturers. So, what are the advantages and disadvantages of each shot?

Double medium coke | Double medium coke is commonly used in flagship machine off-top equipment of some manufacturers. Generally, the bottom of CMOS is relatively large, reaching about 1/2 inches, and the pixel size is generally130,000 ~ 30 million.

Being born in the wrong era is my personal view of dual-media focus. In the era of outsole-oriented design and high pixel-oriented design, double medium focus has become a burden. In the era when the main design area of the outsole reaches11.7 ~11.2, the large photosensitive area can get more light at night than the double medium focus, and the image quality is higher. After double digital zoom cutting and multi-frame algorithm synthesis, the same effect as double medium focus can often be achieved.

Some mobile phones have a main pixel as high as 50 million ~ 200 million, and the resolution of double focal length during the day is even worse than their multi-frame composite cutting. Therefore, the significance of the existence of double medium coke is almost zero.

3 times to 3.5 times telephoto | |79mm This telephoto segment represents the telephoto segment of the mainstream top matching flagship machine and some sub-flagship machine, which is also 3 times. Different pixels and the size of CMOS bottom lead to different imaging quality.

Common CMOS triplets are imx520, ov08a 10, ov64b, ov64bryyb, etc. The size of CMOS ranges from 1/4 to 1/2, but the pixels are the battle between giants and children, ranging from 8 million to 64 million.

Starting from the practicality of mobile phone fixed focus, human scenery is often the most suitable for recording the telephoto of mobile phones, and triple telephoto is just right compared with five or even ten times telephoto. In a narrow city or a village close to the cultural landscape, the triple telephoto is tailor-made for the cultural landscape. Compared with the five-fold telephoto, the triple telephoto avoids the embarrassing situation that the focal length is too long.

Five-fold and 10 | Five-fold and ten-fold telephoto are the most common in the world today, but compared with three-fold, fixed focus of more than five times is often more suitable for shooting natural scenery, and natural scenery is often farther away from the photographer and needs a longer focal length. However, 10 times telephoto will also face scenes with too long focal length when shooting outdoors. So three times ten times is a perfect match for the flagship of all-round photography.
