For photography enthusiasts, it is often found that the scenery seen by the eyes is beautiful, but the pictures taken by the camera are not satisfactory. The main reason for such a difference is that I did not correctly understand the difference between the eyes and the camera imaging, and I could not construct the image captured by the camera in my mind before shooting. If you want to have the perspective of the camera, you must first clearly understand the differences in the imaging of lenses with different focal lengths.
Classification of lenses:
Lenses can be divided into fisheye lenses, ultra-wide-angle lenses, wide-angle lenses, standard lenses, medium-focus lenses, telephoto lenses, and super-telephoto lenses according to their focal lengths.
- Fisheye lens
A fisheye lens is a lens with a viewing angle close to or equal to 180°. It is an extreme wide-angle lens, also known as a fisheye lens because its shape looks similar to a fisheye. The main feature of the fisheye lens is the large shooting angle, and it is for this reason that the captured picture has to be deformed, but this deformation can also bring different beauty.Also read:best iphone fisheye lens
- Wide-angle lens (super wide-angle and wide-angle)
The imaging angle of the wide-angle lens is generally between 120° and 60°. Compared with the fisheye lens, the wide-angle lens can control the deformation of the photo very well, so that the captured picture has a strong sense of stretch. It is generally used for shooting landscapes and can bring Gives a feeling of grandeur.
- Standard lens
The imaging angle of a standard lens is about 45° to 50°. This angle of view is similar to the picture seen by human eyes, so the captured picture is very close to the human eye without stretching or compressing, which means the picture is more real. Lenses with this focal length are also widely used for portraits, cultural photography, and partial landscape photography, with high image quality and blur effect.
- Medium focus lens
The angle of the medium-focus lens is about 43° to 20°. This angle of view has a small distortion of the photo, and it has a longer shooting distance than the standard lens. It can take long-distance portraits and obtain a smaller depth of field.Other recommendations:Best Hand grip Camera Strap
- Telephoto lens
The imaging angle of the telephoto lens is about 12°, and it can shoot distant objects, local close-ups of buildings, long-distance half-length portraits, etc. The telephoto lens has a small depth of field, which means that the background blur effect of the shooting picture will be relatively large , which can highlight the subject.
- Super telephoto lens
The angle of the ultra-telephoto lens is generally lower than 8°. Ultra-long-distance shooting, which is what we usually call zooming in, can bring distant objects closer. This kind of lens is especially suitable for shooting wild animals and birds, and it is also suitable for shooting the actions of athletes in sports events. The big moon we usually see is also shot with super telephoto.
