How to use a fixed-focus lens

Question 1: how to fix the focus with a fixed-focus lens is super good, but it needs to work hard on composition. Zoom basically depends on walking, huh

However, you don't need to be too focused. If Quan Huafu is 50 years old, he must have 85 figures with 28 wide angles.

Practice writing more.

Yes, yes, and in-depth field training.

Question 2: How to use the fixed-focus lens and how to match the aperture speed of the camera? Fixed-focus lenses generally have a large aperture and are cheap. If you like blur, a fixed-focus lens is a good choice. In use, its zoom depends on your feet. In order to better control the depth of field, we generally use aperture priority or manual gear. The size of the aperture depends on the spiritual range you need, not the bigger the better. If you shoot someone and their ears are blurred, that's not good. This requires you to contact more and master the collocation of distance and aperture in order to use the aperture accurately.

Question 3: How to fix the focus? First of all, what is the fixed focus of your lens? 35mm fixed focus is suitable for making records in humanities and highlighting people's main body. 50mmf 1.8 standard lens is the cheapest first choice for you to practice fixed focus, which is suitable for the realism of people and things. 50mmf 1.4 and 85mm lenses are very suitable for close-up of characters, highlighting the noumenon of characters, and are sharp tools for street shooting. It is suggested that you use zoom lens to master shooting from all angles first, and then try to use fixed-focus lens, which will make your composition more rational. PS: Strengthening your ability to measure light with a camera will make the photos look better.

Question 4: Under what circumstances are SLR fixed-focus lenses generally used? What are the advantages and disadvantages? The fixed-focus lens can be used in any situation. Advantages: large aperture, excellent optical design and high imaging quality. Disadvantages: the focal length is single, the composition needs the photographer to move back and forth, and the price is relatively high.

Question 5: How to use the fixed-focus lens? I suggest you sell the camera and lens together: because this camera is really a waste in your hand, you can lose a little if you sell it early, and it will be worthless if you sell it for two years. You don't understand that photography is not a problem. The point is that you are not going to learn photography either.

Question 6: How to make good use of the 50mm fixed focus head I think we should pay attention to the following points:

Tear off the labels of the 50mm lens at most, such as humanity, portrait, standard, documentary, master and Bresson. These things can really explain some characteristics of the 50mm lens, but they will only limit our shooting. In fact, 50mm can be used to shoot almost all subjects (in fact, any lens can "walk the world in one mirror"), not limited to humanities and the like. So, forget these labels and treat them as ordinary lenses. Don't be confused by labels. Try 50mm to shoot different scenes, and you will find more features.

Control the depth of field @ Luo Laima said very well, about the large aperture. Many people buy 50 heads for the cheapest big aperture. It is the first time to use large aperture, which is novel and full aperture anytime and anywhere. In fact, the best aperture of the traditional 50mm lens is often F8 or F 1 1. If the full aperture is reduced by one or two steps, the image quality will be greatly improved. In addition, the vagueness is not the better. Take portraits for example. Jiao Wai's paste is really fresh at first glance, but it is more suitable for taking portraits with large depth of field in some occasions, sometimes close to being photographed, and even the blur brought by F8 is completely enough. Therefore, the so-called "large aperture syndrome" will be solved by trying to control the depth of field according to the subject matter.

Being diligent in walking, we know that the perspective relationship of the photographed picture is only related to the distance between the camera and the photographed object. Therefore, the statement that "the 50mm lens is 35 steps backward and 85 steps forward" is not rigorous. Because in the case that the picture contains exactly the same content, the perspective relationship will be different because of the different distance from the subject. However, this sentence reflects a feature of the 50mm lens, which is a wide range of uses. As long as you are diligent in walking and constantly adjusting the distance from the subject, you can shoot a work with a clear theme and fascinating. Especially friends who are used to focusing, try to walk back and forth as much as possible. Although everyone tends to choose 35mm or even wider when hanging the focus lens now, if I have to choose the lens, it must be 50 mm

Good at composition, 50 mm lens lacks impact. This is a small disadvantage of the 50 mm lens. Compared with the wide-angle all-encompassing breadth and exaggerated distortion, the close-up of telephoto lens and the ability to compress space, 50mm is indeed moderate. Therefore, the 50mm lens has higher requirements for composition than other kinds of focal length lenses, and it needs to work hard on shooting composition and content. Look at how others shoot and master some formatting composition skills. However, we must believe that greatness is born in the ordinary, and the 50mm lens can impress people more with content than skill.

Often used. Okay, I admit I can't make it up. +_+Force yourself to take only a 50mm lens on a trip and try to shoot everything with it. In this way, we will have a deeper understanding of it. Finally, I think taking pictures is a very personal matter, and you don't have to hang a 50mm camera to grow taller. In the past, because there was no money, I hung up 50mm to take pictures. There is a reason: "Without it, I can't shoot it." Similarly, a 50 mm lens can be used without it. There is no need to miss the beauty that should have been captured because of some paranoia or something related to "compulsion".

Question 7: User's guide for 50 mm fixed-focus lens 50mm 1.8 commonly known as small spittoon lens 1. The distance is one to two meters. If it is near, remove the upper part of the forehead; if it is far, it leaves the upper part.

2。 Can be front, side, overlooking (especially attractive angle for women and children, protruding eyelashes and focusing on a single point of eyelid)

3。 Avoid strong light. Don't be in direct sunlight. Indoor natural light by the window, even lighting (pay attention to white balance) is good. The head shows the permeability of the skin, which is very charming. Never kill your skin with a flash.

4。 Focus on your eyes. Single point focusing measurement.

5。 It takes some distance between the photographer and the background to completely blur the background.

6。 Use the continuous shooting function to grasp the expression and shoot five to ten pictures at a time.

7。 With continuous shooting suddenly * * *, it is more valuable to express the most natural expression of life.

8。 Once you find the sense of lens, you might as well overturn all the above and try to create new lens language and visual language.

9. Take a picture with a head. It is suggested to keep in mind the principle of "subtraction" and choose a small scene or a local scene (it is not good to shoot a large scene without a wide angle). Use the 50mm lens language "virtual", use F4 or F5.6, or blur the foreground, or blur the close-up.

10 It's very appropriate and interesting to shoot buildings (parts), windows and sweeping streets with your head.

Question 8: Why use a fixed-focus lens with the same focal length? Generally speaking, there are relatively few fixed-focus lenses because there is no need to consider zooming. When light passes through the medium, it will be lost. For example, imagine that you are 200 degrees short-sighted, wearing a pair of 200 glasses or two pairs of 100 glasses, which is clearer?

In order to pursue high image quality, under normal circumstances, a fixed-focus lens can be preferred. Moreover, the fixed-focus lens is easier to make a larger aperture because of the relatively simple structure of the lens group. The blur of shooting is better, and the amount of light will be greater when shooting.

Question 9: How to set the fixed focus lens? Just set the autofocus lens and camera to am.

Question 10: How to use the fixed-focus lens? It seems that you are Xiao Bai.

A fixed-focus lens means that the focal length is fixed.

The fixed-focus lens will also have a focus ring, which can focus automatically or manually.

The difference with zoom lens is that the focal length of fixed-focus lens is constant, such as 50 mm

The focal length of the zoom lens can be changed within a certain focal length range, such as 70-200mm,
