What are the lenses of SLR cameras? What are the functions of the seven camera lenses?

For some photographers, buying a professional camera is definitely his dream, but many people will be confused when choosing a SLR camera lens, because there are too many lenses for you to choose from. So what lens does the SLR camera have? Next, Bian Xiao introduced the functions of seven different SLR cameras. After understanding, you can choose the lens style as you like.

1. What lens does the SLR camera have?

Photographers are very particular about what kind of lenses to buy. Let's first get a general idea of what lenses SLR cameras have. General SLR cameras should have the following seven kinds of lenses, namely, super wide-angle lens, wide-angle lens, medium-focus standard lens, telephoto lens, fisheye lens, axis-shifting lens and macro lens. You can get to know them.

Second, the role of seven kinds of camera lens:

In the above article, I introduced the knowledge of what lenses SLR cameras have. Next, we will understand the functions of these lenses respectively:

1. Super wide-angle lens

A lens with a focal length less than 24mm is a super wide-angle lens, and its viewing angle is larger than that of a general wide-angle lens, but the imaging will have a certain barrel distortion.

2. Wide-angle lens

The focal length of the wide-angle lens is 24mm-50mm, and this range of focal length can be used to shoot portraits in the environment and some photos of landscape themes. However, the wide-angle lens has higher technical requirements for portrait photography, and it is also more difficult to compose than to shoot.

3. Standard lens with medium focal length

The focal length of a medium focal length standard lens is about 50 mm- 100 mm, which can take portraits and landscapes, but the effect is not very good. On the contrary, it will be better for some goods or still life.

4. telephoto lens

The telephoto lens is mostly used for portrait shooting. For the close-ups of some portraits, the details will be better handled.

5. Fisheye lens

The focal length of the fisheye lens is in the ultra-wide angle range, and the shooting angle reaches 180 degrees or even 360 degrees. It is ok to take some scenery and some business photos.

6. Axis moving lens

Shift-axis lens is different from ordinary SLR lens. The axis of the ordinary lens is vertical to the fuselage, and the lens can be changed according to the situation.

7. Low-power photographic lens

The lenses of SLR cameras all have focal lengths, most of which are more than 30cm. Anything less than 30cm will cause the lens to be out of focus, while the macro lens has a focal length of 3~5cm, which can almost be attached to the surface of an object to take pictures.

Bian Xiao concluded: What kind of lens to choose is believed to be a big problem for many users who buy SLR cameras. Some people may find it difficult to choose which lenses are available for SLR cameras and the functions of seven camera lenses, but after careful study, you will still find out which lens you want.
