Is it better to use fixed focus or zoom for hanging head? what do you think?

Personally, whether to use fixed focus or zoom is based on your own shooting needs and image quality requirements, and there is no strict sense of good or bad, only suitable and unsuitable, otherwise it is meaningless to use fixed focus and zoom at the same time:

The zoom lens has a flexible viewing angle and can adapt to various shooting objects, which is its biggest advantage as a hanging head:

However, the structure of zoom lens is relatively complex, and it is more difficult to control distortion and dispersion, so the imaging quality is slightly weaker than that of fixed focus:

Of course, not all zoomed images are worse than fixed focus. To improve the zoom quality, there are generally the following ideas:

1, reduce the aperture

It is the simplest and lowest cost, which can effectively improve the resolution and suppress the bad phase difference. For example, the common 18- 135 ferrule adopts a floating aperture of 3.5-5.6:

2. Use large-size lens (increase lens volume)

Due to the physical characteristics of the lens structure, the imaging quality of the corner is generally weaker than that of the center, which not only reduces the resolution, but also causes serious dispersion and distortion. Using a lens with a larger aperture can increase the image field area (the size of the imaging circle), cut off the corners with weak imaging, and indirectly improve the average imaging quality of the lens;

Using a lens with a larger aperture makes it easier to increase the aperture and increase the amount of light entering the lens per unit time, which is also the main reason why many large aperture zoom heads are large:

Step 3 reduce the focal length ratio

Reducing the focal ratio can simplify the lens structure theoretically, and it is relatively easy to control the bad phase difference such as distortion. Such as the common big ternary, the focal ratio is below three:

Fixed-focus lenses are simple in structure, relatively easy to control the phase difference, and easier to enlarge the aperture, so the imaging quality is generally superior:

However, the fixed viewing angle is the biggest short board of fixed focus hanging machine, after all, it can only zoom with legs. For convenience of use, the fixed focal length of the hook head is generally short, mainly from wide angle to medium focal length. Taking the full width of 135 as an example, it is generally about 28-50mm;

In order to improve the pertinence of suggestions, it is further divided into two categories: one is photographers or creators who have high requirements for image quality; One is ordinary households with no special requirements. Xiao K is a Nikon user. Take Nikon as an example to talk about the specific model:

1, photographer or creator: wide-angle fixed focus/high-quality zoom (small focal ratio)

Full width: zoom is 24-70/2.8G ED.

It is recommended to consider 28 or 35 for fixed focus, which is more applicable:

28 is wider, more difficult to control than 35, and the perspective deformation is more obvious. Pay attention when choosing. The above lens is also available in 1.8 version, which is more cost-effective.

Half-width: the selection range is slightly smaller, so it is recommended to use 35G, or simply use the full width of 28/ 1.8, which is lighter and the focal length will not be too long. Later upgrades will use:

2, ordinary household: large focal ratio zoom

Ordinary home users, convenience first, taking into account the picture quality:

Full width: 24- 120/4G ED VR:

Half width: 16-80/2.8-4E ED VR:

Is it better to use fixed focus or zoom for hanging head? what do you think?

The so-called "hanging head" generally refers to the lens that photographers often use for shooting convenience, and basically does not need to be replaced by other lenses. This choice is related to personal shooting themes and usage habits, and different people have different choices; When buying a camera, the seller will generally recommend your configuration according to your shooting direction and preferences.

Some people call it the "first shot" or "starting gun".

First of all, beginners should start with the zoom lens. The biggest advantage of zoom lens is that the shooting distance is variable and adjustable. When the composition needs to be close, the focal length can be adjusted to a short focal length. When the composition needs to be far away, you can adjust the focal length to the telephoto end. It can realize convenient expansion and contraction, advance and retreat freely, and avoid the trouble of finding the position back and forth.

Third, when the technology and experience have accumulated to a certain extent, we can consider using a fixed-focus lens. The image quality of fixed-focus lens is obviously better than that of zoom lens in the focal section similar to zoom lens. However, if the fixed-focus lens is used in the new business, it is difficult to find a suitable shooting distance and compare the composition methods of shooting the same scene at different distances. Only when your shooting experience has accumulated to a certain extent, once you arrive at the shooting scene, will you determine the appropriate shooting distance to complete the composition.

Third, it is suitable to choose a lens with a "standard" focal length when shooting portraits. Portrait shooting generally avoids the distortion of characters, which makes people uncomfortable (except in special circumstances). Only the standard lens can meet this requirement, specifically, the focal length is 50- 100. The imaging in this focal length range is basically similar to the visual effect of people seeing the world and things. The picture is neat and tidy, and the effect is more natural, harmonious and cordial, which is also the advantage of shooting portraits with standard lenses.

As for what focal length to choose for your "first shot" and "starting shot", you need to seriously consider it yourself and listen to some suggestions from others before deciding.

Is it better to use fixed focus or zoom for hanging head? First of all, what is an on-hook head?

The so-called on-hook head is the lens that is often hung in front of the lens, that is, the lens with the highest frequency of use. But it doesn't mean that the hanging head must use a standard zoom lens. Still depends on the usual shooting needs.

I believe that most people take a camera with them when they go out, such as 24-70 or 24- 105+50 fixed-focus lens or 85 fixed-focus lens. This combination covers the focal area well at first, and the large aperture fixed-focus lens can be used for low-light shooting or portrait shooting.

A considerable number of people also use a 35mm fixed-focus lens as a suspension lens. First of all, the 35mm lens belongs to a small wide-angle focal length, which can shoot some landscape or cultural works, and at the same time, it can also shoot portraits with a large aperture. Low-light shooting also has great advantages.

There are many arguments about fixed-focus lens and zoom lens, but in fact they don't care about two convenient contents:

Back to the topic itself, the key to choosing what kind of lens to hang depends on your needs. If you only shoot children, you can definitely meet the 35 fixed focus of shooting small scenes on the street. If you are traveling, you need to take pictures of the scenery, and there are also some humanistic close-ups and other needs, it is still recommended to hang a zoom lens. Don't be superstitious about the saying that zoom depends on walking, because even if you shoot enough, the perspective of the picture will remain the same.

Hang up whether it is fixed focus or zoom, the fixed focus is light and the zoom is convenient! It is impossible to hang up an order of 200! Hang up and see your personal preference and shooting type. Let me talk about the benefits of hanging fixed focus zoom!

Fixed focus hang-up-portable and light

Canon users hang more with 35mm, and they also have feelings for lenses like 35mm! Canon 35mm F 1.4 is also my favorite hanging head. The quality there is high, the aperture is large, and it won't be too heavy to hang around your neck. Hanging up for a day is not a problem! Walk more, except for telephoto, basically other lenses can shoot 35 hang-up photos, which is not much different, and it is still a very good hang-up lens! As long as you like, 50mm and 85mm are fine.

Zoom and hang up-simple and convenient

Zoom basically depends on walking, and anti-shake basically depends on hands! This sentence, I think it should be fixed focus basically depends on walking. Relatively speaking, the fixed position of the zoom hang-up machine can take photos of different focal lengths, and the most touching thing is fixed focus! Take a full-frame camera lens 24- 105 or Nikon 24- 120, which is also used to hang still, and you can take more than a dozen photos with different focal lengths in a minute. It's not a bad thing, what's more, it's not too heavy, so it's not a problem to hang it up and go out to shoot. It's really convenient to focus!

The most important thing is that the aperture is not fixed by Jiao Da, and the imaging quality is not as good as that of fixed focus. This is a common problem, there is no way! If the requirements are higher, you can choose 24-70 or 16-35 and 14-24 in the big ternary. The aperture can be several grades larger, the picture quality is slightly better and the blur is stronger!

I have always insisted that what lens to use is related to the theme I choose and the direction of shooting!

However, this option seems a little different. Is to choose between fixed focus and zoom. I think the biggest difference between zoom with the same focal length and fixed focus is the imaging quality: fixed focus has unparalleled advantages in imaging, and the zoom lens is not better than over-fixed focus, but the zoom lens can be easily replaced within a certain range, and the viewfinder under fixed focus replacement can only rely on the legs.

Of course, this proposition depends on the zoom range. For example, compare 80-400x zoom with 105 fixed focal length. It seems that zoom still has some advantages, after all, the zoom range is wider.

However, the so-called hanging head mentioned in the topic proposition is generally full focus 24-70 or 24- 120, and more emphasis is placed on scenery, documentary or portrait. If you focus on landscapes and documentaries, 35 is the best choice. If scenery, documentary and portraits are included, it is of course zooming!

Everything is divided into two, and the right one is the best!

First, sometimes the space is narrow and the distance is limited. Fixed focus, often can't shoot. If it is zoom, it can be realized by wide angle.

Second, you can shoot distant scenes with a telephoto focal length of 200 mm (18-200 lens).

Many friends who have just started to study, the first question is usually what camera they need to buy. Teacher Pu studied calligraphy with a monk at the age of six. I believe that at that time, he would not ask the master what brand of brush he used, nor would he know whether Wang Xizhi wrote with wolf hair or wool. However, this seemingly unanswered question has been turned into almost every photography website by major camera brands and businesses, which has caused many beginners a headache.

But actually owning a camera is only the first step. When you can't use it, holding the highest-end camera is useless except to earn face. Then, you should start to learn and practice various basic skills: exposure, composition, camera control, setting parameters, the feeling of light and shadow, and systematic cognition of color and aesthetics. ..............................................................................................................................

Having said that, it is actually a truth: what kind of head you use has nothing to do with others, but whether it suits your talent! The picture above was taken by a mobile phone.

I like hanging zoom lenses. A lens of 18- 140mm or 18-200mm can basically meet most shooting scenes. Since I hung up, the scene I shot is very different. With the zoom head, the creative means are more abundant.

1, not limited by environment. In some environments, there is no room for moving far and near. For example, if you stand on the overpass and shoot, the distance you can move back and forth is very small. With a zoom lens, you can choose more landscape pictures, while with a fixed focus lens, the space you can create is very narrow.

2. Flexible perspective. The angle of view of a lens depends on its focal length. The longer the focal length, the smaller the viewing angle. When you need a wider viewing angle, you can use the wide-angle end of the zoom lens, and when you need to highlight the main body, you can use the telephoto end of the zoom lens.

3. Special shooting effect. Zoom lens can shoot zoom blur effect.

1. The aperture of the zoom lens is not as large as that of the fixed focus lens. Generally speaking, the maximum aperture of zoom lens is f3.5~f5.6, while the aperture of fixed-focus lens can be 1.8 and 1.4. When shooting in low light, the zoom ratio is not fixed focus, and the control of depth of field is not fixed focus.

2. The zoom quality is better than the fixed focus.

1, creation is restricted by environment. Although the fixed-focus lens can change the scene by getting close to or away from the subject, many times you can't get close to the subject and there is no way to retreat to a farther distance. If the head hanging on the camera was fixed focus, you would want to die. For example, news events were captured by others with zoom, and you cried when you were still looking for the fixed focus position.

2. The perspective will never change. A fixed-focus lens can change the scene by getting close to or away from the subject, but it cannot change the viewing angle.

This allows us to easily capture the scene in front of us, whether it is a super-large scene or a general scene. If it is a little absolute, 90% of the scenes may be shot with such a lens.

The above is my answer, I hope it will help you.
