#Lens
mainly uses lenses with two focal lengths, 50mm and 85mm, when shooting portraits. The biggest difference between them is reflected in the angle of view and perspective deformation.
For example, if the person's position remains unchanged and the two lenses are used to shoot the subject at the same position, it can be seen that the proportion of the person in the picture gradually shrinks, and their blur effects are also different at different focal lengths.
Compared with the 50mm focal length, the 85mm focal length has a smaller viewing angle. 85mm can better integrate the characters and the environment, whether it is blurring or blending the characters and the environment. The 85mm focal length lens is not too close to the model, so the photographer can keep a certain distance from the model without making the model too nervous.
The focal length of 50mm is also very suitable for shooting portraits at an appropriate distance. The angle of view of the 50mm lens is very natural, and the angle of view can show the model's facial features in a very three-dimensional way. The focal length of 50mm is also very suitable for shooting half-length portraits, plus a fixed-focus lens. Because of the relationship, most apertures are at F/1.8 or above, which can easily produce a shallow depth of field effect. In addition, the 50mm is actually more versatile than the 85mm. In addition to taking portraits, it can also take landscapes. It can be said that the 50mm lens is more More practical than the 85mm lens.
And the 50mm lens is relatively short. For the autofocus lens and the lens, it can focus quickly. The 50mm lens is also the standard lens with the largest aperture. It has excellent blurring capabilities and a more natural image field. It can focus quickly and accurately. At the same time, the angle of view is close to the human eye, and you can take pictures with a very comfortable angle of view.
