Mobile phones with extended-out zoom lenses have long appeared, and Samsung launched this kind of mobile phone about ten years ago, and there is even an earlier domestic mobile phone Tianyu C800, but the sales volume is generally not much better.
From the perspective of the year, this mobile phone looks really advanced, and the camera can also be telescopic to take pictures, but today is different from the past, today's mobile phones are not only mobile phones, but also have certain social attributes, the appearance and texture of the mobile phone are very important, no one wants to go out with a brick.
The extended-out zoom lens mobile phone of the year, the thickness is as high as about 2-3cm, and it is inevitably unacceptable to mobile phone users today, and the thickness of the mobile phone is generally about 1cm or even within 1cm, and the manufacturers are more portable than each other's mobile phones.
The extendable zoom lens not only increases the thickness of the phone, but also makes the phone heavier at the expense of aesthetics, and eventually this design is not recognized by users and is eliminated from the market.
Another point, mobile phones belong to portable handheld devices, to pursue thin and light Now in order to make full use of the internal space of the mobile phone, manufacturers have designed the battery to be built-in, and even canceled 3The 5mm headphone jack is to make the phone thinner and lighter.
Not only the extended-out zoom lens, but also the previous flip-type lens, as well as the lifting lens, have also been eliminated, mainly because the mechanical parts occupy the internal space of the machine, and now the mobile phone is getting thinner and thinner, and it is impossible to leave a place for the mechanical parts.
In order to reduce the failure rate, mobile phone manufacturers have been trying to minimize mechanical parts, mobile phones are devices that need to be moved frequently, and too many internal mechanical parts will inevitably lead to a high failure rate, and the extendable zoom lens design will increase production costs and later maintenance costs.
The complex mechanical structure of the extendable zoom lens requires a precise mechanical structure and a complex control system, which undoubtedly increases the production cost and research and development difficulty of mobile phones.
This design also makes the overall design of the phone more complex, and the thickness and weight of the body will also increase. This is unacceptable for smartphone users who pursue a thin and light design concept.
Extended-out zoom lenses can affect the phone's overall aesthetics and grip when extended. Frequent protrusion and retraction can lead to wear and tear on the mechanical structure and reduce the service life.
The telescopic lens will also affect the waterproof performance of the mobile phone, not to mention putting it in the water, even a little rain may enter the inside of the mobile phone through the lens gap. Obviously, not many users will sacrifice water resistance for zoom ability.
The lens set also results in an increase in volume and no space for placement. At present, mainstream mobile phones still have an approximate thickness range, and the telescopic lens will greatly increase the volume of the mobile phone after it is extended, which is much longer than some current flagships.
