Feelings of Xiaomi Photography Institute

Yesterday, Xiaomi released a new mobile phone lens achievement-telescopic large aperture lens.

Adam Gao, vice president of Xiaomi Group and president of mobile phone department, mentioned two characteristics of the lens: one is the super-large aperture, and the other is the introduction of a brand-new anti-shake scheme.

Needless to say, the anti-shake scheme. Friends who like taking pictures all know the benefits of this.

It is worth mentioning the characteristics of "super aperture". Friends who don't have a deep understanding of photography technology may not quite understand what promotion this super aperture will bring to photography. In this regard, you can simply explain:

First of all, a large aperture can increase the amount of light entering the lens. According to Adam Gao, this kind of lens can increase the light input by 300%. Increasing the light input has two advantages: first, it can improve the shutter speed, obviously play an anti-shake role, and can better capture wonderful moments when shooting moving objects. The second is to improve the shooting experience in low light environment, so that mobile phone photography can adapt to a variety of scenes. For example, at night, shopping malls, cafes and so on.

Second, the ultra-large aperture can have a shallower depth of field. The depth of field can be simply understood as the blurring of the photo background, and the depth of the scene means that the blurring of the background is more obvious and can better reflect the shooting theme. Especially when shooting portraits, shallow depth of field can eliminate the messy background and focus on the portraits. At present, the portrait mode on mobile phone is more realized by simulation algorithm to reflect the background blur effect, rather than the real optical blur, so the effect is not ideal in some scenes, and sometimes the blurred background is better.

We also know that since the lens was put into the mobile phone, people have made a lot of efforts to improve mobile phone photography in order to achieve the effect of SLR photography. Many mobile phone manufacturers have long had the idea of applying the telescopic technology of SLR camera lens to mobile phones, such as Nokia and Samsung.

Typical model: Samsung K Zoom

Samsung K Zoom mainly promotes optical zoom in mobile phone photography, which simply means to bring the subject closer and farther (it can be said that although this is a 20 14 product, there is almost no opponent in mobile phone telephoto photography, whether Huawei or Xiaomi claims how many times the zoom can be achieved). But it didn't further improve the aperture coefficient. Now it seems that this product is really not very beautiful and inconvenient.

Generally speaking, the telescope head is basically a manifestation of zoom, but the telescopic large aperture lens released by Xiaomi does not clearly explain what changes have been made to zoom and how much it has improved the camera. We still need to wait until it really enters the market.

The only thing that can be determined now is that if the lens can really be so mini, it will look better than Samsung K zoom in appearance, and of course it will be more convenient.

Finally, be proud. At present, no mobile phone can kill my 20 10-year-old antiques in photography quality.
