What is the standard lens suitable for shooting?

Question 1: What is the 50mm standard lens of SLR mainly used for shooting? Well ... well, I'll introduce you to some basic knowledge, and I hope you can find the answer from it ~

Let's talk about the focal length of the lens first ~

The smaller the focal length, the larger the shooting range (wide-angle lens) ~ The larger the focal length, the smaller the shooting range (telephoto lens)!

As shown in the figure:

Then it's time to discuss portraits ~

Why are some shots more suitable for taking portraits? The reason is in the following figures:

This is a screenshot of a photo taken by the same person at the same distance and different focal lengths. Look carefully at her nose ~ ~ ~ Is it big or small?

Yes, your eyesight is very good!

The reason is the distortion of the lens! The smaller the focal length, the more serious the distortion, and the larger the focal length, the smaller the distortion!

[This is a wide angle and the distortion is very serious]

[This is the lady just now, lens focal length 135 (medium telephoto)]

So, that's why people call a lens with a focal length of 85- 135 a portrait head! (So it is necessary to take photos. )

Does that mean you can't take portraits with a lens before 85mm?

Of course not ~

There are two situations: one is when the wide-angle effect is needed, and the other is when it is far away from the lens (which can reduce the influence of distortion).

Finally, tell me about your machine with a lens ~

Pentax KX belongs to APS-C camera, and the lens focal length needs to be multiplied by the conversion coefficient of 1.5 to be the actual focal length ~

Your 70-2 10 lens is quite suitable! But without a wide angle, it is not enough to shoot architecture and tourism ~ I suggest adding a wide angle ~

50mm fixed focus, excellent imaging effect! Big aperture, buy it ~ it's good for upgrading technology ~

The head clarity of 50mm is the closest to the human visual angle ~ perhaps it is the reason why it was changed to 75mm in the post-APS-C era, so it is closer to the focal length of the portrait lens, so many people call it "portrait head" a bit far-fetched ~

In addition, there is no limit to the focal length of the scene, any lens with focal length can shoot the scene ~ ~ What kind of scene can be shot with what lens, which has nothing to do with the best focal length of the portrait ~ If it is insisted that it is suitable for shooting the scene, then I think it is quite suitable! Especially when shooting the night scene at night, how beautiful it is to turn the highlight of the street lamp into a circle with a large aperture!

Novice, it is most important to master those apertures, shutters, light and exposure first ~ because this is the basis of all shooting.

Question 2: What are the classifications of SLR lenses? What are they suitable for shooting? What is a wide angle? Wide-angle 12MM-35MM is generally used to shoot large scenes, because the picture covers a lot of content, and the title of 35-80 can generally shoot anything, which is closest to human vision. Then the focal length is 85MM- 135MM, which is suitable for taking portraits. Because this focal length is not easy to be distorted, it looks very comfortable. Above 135MM, it is a telephoto, 50-60 macro lens, and 100 macro lens is more suitable for macro shooting.

In fact, there are no strict restrictions. You can only shoot what you say. Decide the usage of the focus segment according to the theme of the effect you want to show. For example, the telephoto lens looks compact and blurs the main body. Large aperture is also a strong blur ability.

Question 3: What is a 50mm lens suitable for shooting? The 50 mm lens is the standard lens on a full-frame camera, and its viewing angle is similar to that of the human eye. The perspective effect of the photos taken is close to the human eye, which can restore the scenery more truly.

A 50 mm lens is multiplied by a coefficient of 1.5 or 1.6 on an APS camera, which is basically equivalent to a lens of 75 or 80 mm and belongs to a small medium focus.

Question 4: What subjects are suitable for telephoto lens shooting people, birds and wild animals? It depends on the specific focal length.

A long focal length lens refers to a photographic lens whose focal length is longer than that of a standard lens.

Telefocal lenses are divided into ordinary telephoto lenses and ultra-telephoto lenses.

The focal length of ordinary telephoto lens is close to that of standard lens, while the focal length of ultra telephoto lens is much larger than that of standard lens. Take 135 camera as an example, the photographic lens with a focal length of 85 mm-300 mm is a normal telephoto lens, and the lens with a focal length of more than 300 mm is a super telephoto lens.

A telephoto lens has a long focal length, a small viewing angle and a large image on the negative. Therefore, at the same distance, you can take larger images than the standard lens. Suitable for shooting distant objects. Because its depth of field is smaller than the standard lens, it can blur the background more effectively and highlight the focused subject, and the subject is generally far away from the camera, which makes the portrait more realistic in perspective, so people often call the telephoto lens a portrait lens. The telephoto lens is often used in professional photography because of its long lens barrel, heavy weight, relatively expensive price and small depth of field, and it is difficult to focus in practical use.

Question 5: What lens is the most suitable for SLR cameras to take portraits? 85- 135mm is the most suitable focal length for portrait shooting, which is in the textbook of New York Institute of Photography. Canon's best lens in this respect is 85 F 1.2 and Nikon's is 85 F 1.4.

Question 6: What is a telephoto lens suitable for shooting? But separately, under the same aperture, the telephoto depth of field is smaller.

Under the same aperture and focal length, the depth of field of any lens is the same.

However, the standard fixed-focus lens (that is, the lens with a focal length of 50MM) usually has a larger aperture, which can obtain a larger blur effect (for example, 50 1.8 600 yuan, 50 1.4 2000 yuan, 50 1.2L 10000 or more). )

In addition, it is suggested that if you take outdoor portraits, you can consider two cost-effective lenses, 85 1.8, and the price is about 2600. 135/2L, about 6K. Clear central resolution and soft Jiao Wai effect can be obtained. The focal length is also suitable for taking portraits.

Question 7: 50 1.8 What is the suitable lens for shooting? 50mm is the meter head, as the name implies, is the standard lens. The vision it sees is very close to the monocular vision of people, that is, people can shoot whatever they see. So it is very popular. It has a wide range of uses, and the scenery is suitable for everyone. However, its disadvantage is obvious, that is, the field of vision is too ordinary, which will give people a sense of mediocrity, especially when shooting the scenery, it will not be as imposing as a wide-angle lens, but perhaps it is the mediocre perspective that makes the photographer pay more attention to the internal content of the picture. Many photographers also prefer 50 mm-the lens recommended for you is Longteng's17-50 mm/F2.8, which can take into account the scenery.

Question 8: How does a standard lens SLR camera get such an effect in the picture? The lens can be expressed according to specific parameters, but it is not a standard. The effect of this picture can be achieved with the common 18 mm and 24 mm ends. I said these two parameters only for your convenience to find this lens. If you like to shoot this kind of scenery and the budget is not high, you can use a lens like 18- 135.

Question 9: 18-55 What is the suitable lens for shooting? 18 lens can take a wide-angle view, and 55 lens can take some photos of life, which can be used normally. If it is necessary to shoot portraits with blurred backgrounds, there is no way out. It is better to add 50 1.8 or 50 1.4 to 18-55.

Question 10: What is the Canon 18-55 lens suitable for shooting? 18-55 ptz is a standard zoom lens, including a wide-angle end and a standard focal length. The wide-angle end is suitable for shooting scenes, and the 55th end can be used for shooting portraits. Because the focal length is too short, it is not suitable for telephoto.
