Which focal length is most suitable for portrait photography?

Both of these are good, provided they are used on full-frame film SLRs.

D80 with 85 to shoot portraits, the focal angle angle is very embarrassing, long is not long to say short, and it is awkward, the imaging quality is not as excellent as many people say, and the metal head, the processing accuracy is not enough, the sealing is not good, and it is easy to enter the soil. Among the 85 portrait lenses of each family, Nikon, which makes the worst one, has a lack of oiliness and sharpness, and the focus is dry and stiff, compared with Binder 77, it is a big difference, but it is not cheap in the 6500 rank.

50 In addition to being cheap, there are no features at all, the front section of the focus is rotated, the lens is small, the feel is poor, the comprehensive imaging is medium to high, the aperture imaging is very soft, very loose, the image is uncertain, and the effect is not bad when it is shrunk, but when shooting portraits, the aperture used for the focal length of 50, how can the background be blurred?

If it's an F80 portrait lens, I wouldn't hesitate to recommend 85, but it's a bit difficult to put it on the D80 body with a coefficient, weigh it, according to your own frequency of use, 50-135 may be the best choice.

Now Tuli 50-135 **4200 yuan, it's quite affordable.

Generally, more than 80 is fine, if you want to better highlight the subject and blur the background, you can choose a higher one, such as 200, etc.

Personally, I recommend 85mm, I have used both of these heads, for the performance of portraits, 85mm heads are better. But the difference between the two heads is not as big as the difference between the **. If you have rice, you will go up to 85mm, and if you have an economic point, you will go up to 50mm.

And how can a photographer not have a 50-header.

It can't be said which lens is better for portraits, for example, wide-angle portraits are very popular right now.

85 is definitely the best choice, I just use this, and a few of the guys around me who take portraits also use this, and the response is very good, it must be right.

The landlord's request is a bit vague!! Portraits are divided into two types: environmental portraits and portraits, if it is a portrait, you must use an 85mm lens, if it is a combination of people and the environment, then a 50mm lens is enough.

The 50mm lens is still slightly distorted when taking portraits, mainly due to the disproportionate ratio of ears and face when shooting from the front.

And 85mm will not have this phenomenon!

Portrait refers to the face above the bust that accounts for the vast majority of the picture! Close-up of the face.

Portrait prime lenses of 50mm are better. 50mm has a certain bokeh effect, and it will not be like 35mm, which needs to be very close to produce a more satisfactory virtual aging. 50mm shooting portraits has a certain ability to narrate scenes.

Like 85mm, it's a bit narrow, especially the indoor grinding cover 85mm, most of which can only take half-length or headshots, and rarely can ** the environment.

The perspective of 50mm is more natural, it doesn't have a slight tension on the 35mm, and it doesn't have the slight compression of space on the 85mm. 50mm seems to be as plain as water as the human eye is swimming, and there is no "emotion" for ** from the perspective of view. Of course, there are also friends here who say that it is easy to have no characteristics, which is a common problem.

Precautions for choosing a lens for shooting portraits.

When shooting portraits, choosing a lens with a larger aperture can make people's ** more delicate; Moreover, in the face of a cluttered background, you can blur the background to make the picture cleaner and highlight the subject of the portrait; Large-aperture lenses are also more advantageous when shooting in low-light conditions. So when choosing a lens, choosing a large-aperture lens is the first choice. The focal length of the lens also has different options for portrait subjects, and it is best to shoot landscape portraits with a wide-angle and large aperture lens, such as 16-35mm, 35mm, etc.

Focal length is a measure of the concentration or divergence of light in an optical system, which refers to the distance from the center of the lens to the focal point of the light concentration when the parallel light is incidence. Optical systems with short focal lengths have a better ability to concentrate light than those with long focal lengths.

In simple terms, focal length is the distance between the focal point and the center point of the mask. In the camera, the focal length f "image distance< 2f can be imaged.

Focal length refers to the range of changes in the focal length of a zoom lens. The division of the focal length of the lens: the first is the header, which is the so-called standard lens. Its angle of view is around 43 degrees, and the perspective of ** at this time is closest to the human eye.

Depending on the frame, the focal length of the header is also different. The standard lens of 135 frames is around 50mm, the 6 of the 120 has a focal length of 80mm, and the head of the 300D is around 50.

Whenever a new friend who is just getting started asks this question, many so-called professionals recommend 85mm, 105mm 2, 135mm 2, etc., this kind of medium and telephoto prime lens.

It is said that the imaging is sharp, the background is blurred well, and it is very resistant to zoom, saying that photographers should not shoot if they are afraid of trouble.

Is that really the case? I don't recommend using a prime lens above 85 to shoot people, because on digital machines, 85 is equivalent to a focal length of 127 136mm, and if it is longer, such as 135mm, if you want to shoot a whole body, you have to step back more than ten or twenty meters, which is really inconvenient to communicate with the subject.

I think that new friends, the concept of focal length is very vague, you should use a standard zoom head first, the focal length is between 28-85mm, (in fact, the most commonly used focal length I photograph is the focal length between 24-70mm, so that the composition is more convenient and flexible.) Perhaps this statement is very different from the statement of the 85-135mm focal length of the domestic Shengchuan) and wait to be familiar with these focal lengths before buying a prime lens for a specific focal length.

Some people say that fixed-focus imaging ***, I don't deny this, but how big of a difference can it be? If you don't zoom in to 18 inches, can you see a clear difference? If you are not a professional commercial photographer, you will not care too much about the loss of zoom lens image quality, or the portrait of a photo studio.

And it is worth sacrificing a little bit of image quality in exchange for the flexibility of composition and saving the trouble of changing lenses.

There are also people who say that using a fixed focal head can calm people's hearts, devote themselves to photography, zoom, and composition are all coming out, and the zoom head will make people impetuous, and they will stay in place and only rely on zoom pulling, and the composition will be more rigid.

I think this statement is very incorrect, if an impetuous person, with a fixed focus head, he can't calm down, always thinking about changing the lens, a day is wasted on changing the lens, and it will damage the machine, and the CCD will go into dust. If a calm-minded person uses a zoom head, he will also walk back and forth to frame the frame, and he can freely choose different focal lengths according to each scene, and he will not always think about changing lenses.

Therefore, professionals should stop recommending medium telephoto fixed focal points to newcomers, this may just be your personal preference, don't mislead newcomers, and make others feel that these fixed focal points are necessary for shooting people.

Classification and analysis of portrait lenses, which lenses are more suitable for you?

Cameras of various specifications, according to the size of the camera imaging frame, will be different for the most suitable focal length for shooting portraits, to determine whether a lens is suitable for shooting portraits, the principle is that the lens between this focal length segment, the perspective deformation generated, the most in line with the requirements of people to observe the facial features when observing the close-up of the person, there will be no nose, forehead and other parts too prominent or exaggerated problems, at the same time, in this focal length, the portrait can fill the whole picture when the close-up of the person is photographed, However, it is not called a portrait lens with a small distortion, because with some telephoto lenses, in order to fill the picture with the subject, there must be too far away from the subject, which will make the subject have an adverse psychological reaction of "being thousands of miles away from people", so it is generally considered that the portrait lens is more suitable for the medium focal length.

In a full-frame 35mm camera, the focal length for portraits is 70 135mm, and for larger large-format camera lenses such as 120, the focal length for portraits is 90 180mm, for APS frames it is 45 85mm, and so on.

However, some portable cameras that use smaller size image sensors, because the CCD image sensor is different in size, and the difference is too large, and there are many models and varieties, and the focal length of the lens required will also vary greatly due to various specifications of cameras, in order to facilitate production, manufacturing and consumer purchase, most camera manufacturers now generally use the annotation method of converting to the corresponding focal length of the full-frame 35mm camera, so we only need to remember the focal length of 70 135mm required for full-frame camera portrait photography. You can measure whether the focal length of the lens equipped with the portable camera you choose meets the requirements of the portrait you want to shoot.

Classification and analysis of portrait lenses, which lenses are more suitable for you?

Lenses with focal lengths of 16mm to 200mm, which are commonly used for portraits, are capable of using prime for posing and zoom for snapshots.

Wide-angle lens: large viewing angles, can shoot large scenes, objects near and far small, vertical objects are pushed away from each other, and the ability to blur the background is weak.

Taking advantage of the wide angle of view of its digital camera, it can express large scenes and shoot atmospheric pictures. To avoid large distortions, avoid placing the subject too far on the edges when shooting portraits with an ultra-wide lens.

Medium-focus lens: The perspective is natural, similar to what the human eye sees, and the bokeh ability is significantly stronger than that of wide-angle lenses.

When using a mid-focus lens to shoot people, because of its natural perspective, the angle of view is not too big or small, and the picture is easy to appear "flat", so it is best to choose some characteristic on-site elements to get a glimpse of the whole leopard and explain the environment.

Telephoto lens: The smallest angle of view, can zoom in on distant objects, the distance between vertical objects is "closer", and the ability to blur the background is the strongest.

When the background or foreground is far away from the person and you want to emphasize the relationship between the two, you can use a longer focal length to "compress" them together.

Physically, the definition of focal length is the distance from the center of the lens to the focal point, and because the photographic lens adopts a multi-lens structure, the meaning of focal length is more complex than the physical definition of a single lens.

The photographic process is the process of imaging the photographed object to the sensor (negative) through the lens, the distance between the photographed object and the theoretical lens surface of the lens is the object focal length, and the distance from the theoretical lens surface of the lens to the sensor is the image square focal length.

The focal length of the lens usually refers to the image square focal length, and the essence of the photographic focal length refers to the angle of view of the shooting picture, and the larger the focal length, the smaller the viewing angle.

The change in focal length does not affect the sharpness of the image, but rather the size of the image range.

Sharpness is the problem of focusing, which has nothing to do with focal length, focusing is to make the focus of the imaging fall on the sensor, as long as the focus is accurate, no matter what focal length the imaging is clear.

The focal length is for the zoom lens, and the focal length of the zoom lens is variable in a continuous range, so the minimum focal length and the maximum focal length are written together, which is called the focal length.

The focal length is the distance from the lens to the plane of focus, have you ever played with a magnifying glass to roast ants in the sun? The distance from the magnifying glass to that smallest bright spot can be understood as the focal length. The focal length is easy to understand with a zoom lens, such as an 18-200mm zoom head, you can say 18-200mm focal length.

Focal length is the distance between the subject and the lens! The focal length is the distance between the maximum and minimum values in the zoom lens!
