Can the camera "squeeze toothpaste" and the lens "squeeze toothpaste"? Sure! Tell you something you don't know.

The camera can squeeze toothpaste, and the lens can squeeze toothpaste. Of course! And it can "squeeze toothpaste more concealed"

Let's first understand the meaning of "squeezing toothpaste". The so-called "toothpaste squeezing" means taking out new technologies and functions bit by bit in the upgrading of photographic equipment, just like "toothpaste squeezing". This premise is that the manufacturer obviously has some new technologies and functions, which can be used in the current equipment, but in order to obtain the maximum benefit, he is unwilling or plays with some means to slowly take out these technologies and functions that can be used for a long time. As for the origin of "squeezing toothpaste", it is difficult to research, because it is commonly known as this, and there are many noises. Haha, it doesn't matter who invented it first. What is important is that "squeezing toothpaste" makes people understand that all businesses are unscrupulous, so we should exercise restraint and consume rationally.

"Squeezing toothpaste" is more of a camera, because the camera structure is relatively complex and has more functions, so the places where manufacturers squeeze toothpaste are naturally very extensive. But the problem of "squeezing toothpaste" is also very common on lenses. Modern lenses are highly electronic and have complex functions, so it is more convenient to "squeeze toothpaste".

It is not easy to improve image quality and reduce aberration, but it is very simple to make aberration. In the design, it is found that the optical quality can be quite unusual by determining the optical system, but due to the development and positioning of this lens, it is unwilling to obtain such excellent optical imaging. In order to prevent the impact on this manufacturer's higher-end series of lenses, deliberately creating point aberrations, that is, lowering the final imaging level, is not fabrication. This practice also belongs to "squeezing toothpaste", which is very hidden!

If some low-end lenses are designed with unexpected high quality and have been put on the market, I'm sorry, this kind of high-quality low-end lenses can be withdrawn from the market, so as not to cause adverse effects on their own series of lenses. As for the interests of users, it is completely secondary (examples are not given for the time being).

In terms of lens function and material, the lens barrel is made of engineering plastic, the bayonet metal is replaced by plastic, the coating is degraded to reduce the number of layers, the special optical glass is used less, the aperture range is reduced, the anti-shake series is limited, and the focusing motor gives up the micro or ring motor technology to replace the ultrasonic motor. There are many kinds of patterns, all for the benefit.

In fact, cameras and lenses really don't need so many models and specifications; There is no need to upgrade new products so frequently; The constant tossing of manufacturers is entirely based on their own interests. The purpose of "squeezing toothpaste" is to "make you never get more comprehensive and perfect equipment", that is, "make you never get satisfied and dissatisfied" In this way, they keep developing, producing and making money! As for consuming the earth's resources, as for destroying the ecological environment, as for consumers' unnecessary excessive consumption and losses, it is second, let them go to hell.

Photography consumers should keep their eyes open, face rationally and protect the earth's resources and environment.
