What is a standard lens suitable for shooting?

Question 1: What is the 50mm standard lens of a SLR mainly used for shooting? Well... let me introduce some basic knowledge to you, I hope you can find the answer~

Let’s start with the focal length of the lens~

The smaller the focal length, the better The larger the range that can be photographed (wide-angle lens) ~ the larger the focal length, the smaller the range that can be photographed (telephoto lens)!

As shown in the picture:

Next, it’s time to discuss portraits~

Why are some lenses more suitable for portraits? The reason is in the pictures below:

These are screenshots of photos taken by the same person at the same distance with lenses of different focal lengths. Look carefully at her nose~~~ Does it look bigger? Small?

Yes, your eyesight is very good!

The reason lies in 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, the distortion is very serious]

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

So, This is why people call the 85-135 focal length lens a portrait lens! (So ??it must be used when taking *** photos)

Does that mean that lenses before 85mm cannot take portraits?

Of course not ~

Two situations: one is when a wide-angle effect is needed, and the other is to be farther away from the lens (which can reduce the impact of distortion)

Finally, let’s talk about the lens you use with this camera~

Pentax KX is an APS-C camera, and the lens focal length needs to be multiplied by a conversion factor of 1.5 to get the actual focal length~

< p> Your 70-210 lens is quite suitable for shooting***! But it lacks a wide angle, which is not enough for shooting buildings, traveling, etc. It is recommended to add a wide angle~

The 50mm fixed focus, the imaging effect is excellent! The aperture is large, buy it~ It is beneficial to the enhancement technology~

The definition of 50mm lens is the closest viewing angle to the human eye~ Perhaps it has been changed to 75mm in the post-APS-C era , so it is closer to the focal length of a portrait lens, so many people call it a "portrait lens" far-fetched~

In addition, there is no focal length limit for shooting landscapes, and any lens with any focal length can shoot landscapes~ ~~What kind of lens should I use to shoot what kind of scenery? It has nothing to do with the best focal length for portraits~ If I have to say whether it is suitable for shooting landscapes, then I think it is quite suitable! Especially when shooting night scenes at night, using a large aperture can turn the bright spots of street lights into circles. How beautiful!

As a beginner, first master the aperture, shutter, light, exposure, etc. are the most important ~ because this is the basis of all photography.

Question 2: What are the classifications of SLR lenses? What are they suitable for shooting? What is wide angle? Wide angle 12MM-35MM is generally used to shoot large scenes, because the picture covers a lot of content. What is usually header 35-80? It is the focal length that is closest to human vision. Then there is the focal length suitable for portraits, 85MM-135MM, because this focal length is not prone to distortion and looks very comfortable. 135MM and above are telephotos, and 50-60mm micro lenses. The two focal lengths, macro lens of 100mm and 100mm, are more suitable for macro photography

In fact, there is no strict limit on what you can only shoot. Determine the usage of the focal length according to the effect theme you want to express. For example, the film looks more compact when taken at telephoto, and the blur can better highlight the subject. The large aperture also has strong blurring capabilities.

Question 3: What is a 50mm lens suitable for shooting? The 50mm lens is a standard lens on full-frame cameras. Its angle of view is similar to that of the human eye. The perspective effect of the photos taken is close to that of the human eye, and it can be more realistic. Restore scenery.

A 50mm lens needs to be multiplied by a factor of 1.5 or 1.6 on an APS format camera, which is basically equivalent to a 75 or 80mm lens, which is a small and medium focal length.

Question 4: What subjects are suitable for photographing with a telephoto lens? Photographing people, birds and wildlife depends on the specific focal length.

A telephoto lens refers to a photography lens that has a longer focal length than a standard lens.

Telephoto lenses are divided into two categories: ordinary telephoto lenses and super telephoto lenses.

The focal length of an ordinary telephoto lens is close to that of a standard lens, while the focal length of a super telephoto lens is much longer than that of a standard lens. Taking the 135 camera as an example, the photography lens with a focal length from 85 mm to 300 mm is an ordinary telephoto lens, and the one with a focal length of 300 mm or more is a super telephoto lens.

A telephoto lens has a long focal length, a small angle of view, and a large image on the film. Therefore, it can capture a larger image than a standard lens at the same distance. Suitable for shooting distant subjects.

Because its depth of field range is smaller than that of a standard lens, it can blur the background more effectively and highlight the subject in focus. Moreover, the subject is generally far away from the camera, resulting in less distortion in the perspective of the portrait, making the portrait more vivid. , so people often refer to telephoto lenses as portrait lenses. However, telephoto lenses have longer barrels, are heavier, are relatively more expensive, and have a relatively small depth of field, making it difficult to focus in actual use, so they are often used in professional photography.

Question 5: What lens is best for taking portraits with a SLR camera? 85-135mm is the most suitable focal length for shooting portraits. This sentence is found in the textbooks of the New York Institute of Photography. Canon's best lens in this regard is the 85 F1.2, and Nikon's 85 F1.4.

Question 6: What is suitable for shooting with a telephoto lens? A telephoto lens is smaller, but let’s talk about it separately. Under the same aperture, the depth of field of a telephoto lens is smaller.

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

However, standard fixed focus lenses (i.e. lenses with a focal length of 50MM) usually have larger apertures and can achieve greater blur effects (for example, 501.8 is 600 yuan, 501.4 is 2000 yuan, 501.2L is 10000 yuan or more. )

In addition, it is recommended that if you take outdoor portraits, you can consider two more cost-effective lenses, namely the 851.8, which sells for about 2,600. 135/2L, selling for about 6K. You can get sharp center resolution and soft bokeh effect. The focal length is also more suitable for shooting portraits.

Question 7: What is the 50 1.8 lens suitable for shooting? 50mm is a masthead. As the name suggests, it is a standard lens. The field of view seen with it is very close to a person's monocular field of view, that is, what a person sees. What kind of photos can be taken in this way. So it is very popular. It has a wide range of uses and can be used by everyone to take pictures of landscapes. However, its shortcomings are also obvious, that is, the field of view is too ordinary, which will give people a sense of mediocrity, especially when shooting landscapes. It will not be as impressive as a wide-angle lens, but maybe it is the mediocre perspective that makes it so. This makes people who appreciate photos pay more attention to the inner content of the picture. Many photography masters also prefer 50mm - the recommended lens for you is Tamron's 17-50mm/f2.8. With it, you can take into account the scenery

Question 8: How can I use a SLR camera with a standard lens to achieve the effect in the picture? The specific parameters of a lens cannot be expressed by one standard. This picture effect can be achieved with the more common 18mm and 24mm ends. I mentioned these two parameters just to make it easier for you to find this lens. If you like to shoot this kind of For landscapes, if the budget is not high, you can use a lens like the 18-135.

Question 9: What is the 18-55 lens suitable for shooting? The 18-end wide-angle lens can take pictures of landscapes, and the 55-end lens can take some daily life photos. Use it normally. , if you need to take portraits with a blurred background, there is nothing you can do. It would be better to add a 50 1.8 or 50 1.4 to the 18-55.

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