What does a cell phone SLR lens do?

Single lens reflection. A camera using this technology has only one lens, which is used for both photography and framing. Only in this way can the problem of poor photo quality caused by parallax be fundamentally solved. Moreover, when shooting a view with a SLR camera, the light emitted by the object is focused by the lens, reflected by the oblique mirror to the focusing screen for imaging, and then reflected by the "roof prism" raised at the top. Photographers can see the scene through the eyepiece, and it is the same image as the scene, so it is very convenient to focus on the scene.

Judging from the responsibility of the fuselage and the lens, it is generally believed that the lens plays a greater role in image quality, accounting for about 65%. So when buying a machine, the price ratio is also divided in this way.

We didn't even know about the external lens of the mobile phone before. With the popularity of using mobile phones to take pictures, external lenses quickly became popular. "Cyclops" four-in-one camera lens is equipped with four advanced optical lenses (fisheye, wide angle, 10 macro and 15 macro, 50m telephoto and1500m telephoto). The front camera and the rear camera are perfectly matched, making it easy to take distinctive photos and selfies, making your mobile phone SLR in one second.

Shooting with an external lens of a mobile phone also has a SLR effect. In today's information age, science and technology are constantly developing and progressing.

The image taken with external lens is as good as professional SLR camera (fisheye, wide angle, macro).

Some people say that the external lens is not very practical, and Bian Xiao would like to mention it. Do you still remember Wong Kar-wai's movie fallen angels, in which a large number of fisheye lenses are used, which can reflect people's psychological activities in facial description? Of course, the images taken by this lens enhance the appeal of the picture, emphasize the perspective effect of the picture, and are good at exaggerating the foreground and expressing the sense of distance of the scene. The reproduction of the scene texture will also give people an image shock. Another example is wide-angle. When a photographer needs to shoot a large area of pictures, but there is no way, he uses a wide-angle lens. The wide-angle lens is characterized by short focal length and long depth of field, which can shoot a larger picture. The images taken by the external lens of the mobile phone bring us another style of painting and pleasure, which makes us learn to appreciate and increase our knowledge.
