What focal length is most practical for a telephoto lens

At present, the main focal length of the telephoto lens is 200mm and 300mm, under the premise of ensuring the shooting effect of the lens and the anti-shake performance, it must be the 300mm telephoto lens is more worthy of choice, but I don't know the budget of the landlord to buy the lens, for most photography enthusiasts, 200mm is completely enough, so it is not possible to say that the telephoto lens of the focal length is better, or you need to choose according to the actual situation of the landlord and the performance of the lens.

Remember.

The Nikon D80 kit is good. The 18-135mm wide angle can be used to shoot landscapes and humanities, and the portraits of medium focus can also be taken into account the stage and concerts that are slightly farther away. However, the shooting quality is average, and it is not as good as the prime lens. If you add a portrait head, it will cost only 3,000 yuan to solve the problem.

If you want to shoot with better quality, you can choose option 2:

Yuan. Yuan. This configuration focuses on good imaging, and the part with insufficient focal length can be completed by moving two more steps by yourself, and the rest of the funds can be invested in accessories such as tripods and camera bags.

If the funds are sufficient, a small bamboo cannon can be configured, and a lens gold wide angle is about 20,000 yuan.

There's really no way, and you don't give the budget money. I had to estimate the high, medium, and low to be considered dedicated.

The role of a telephoto lens is as follows:

1. Zoom in on the subject.

When shooting distant objects, using a telephoto lens allows the subject to zoom in and create the feeling of zooming in on the lens. For example, when shooting distant birds, use a long focal length to fill the frame to achieve the effect of zooming in. Sometimes the content of the picture is too cluttered, use the telephoto to zoom in to make the picture concise and remove the content of the picture that we don't want.

2. Compress space.

When we shoot landscapes, the spatial distance between the near and far shots is far apart, and the use of a telephoto lens can shorten the spatial distance between the long and close shots, and the distant scenes in front and back can be shot with a compact picture effect.

3. Background blur.

The longer the focal length, the farther away the subject from the background, the shallower the depth of field, and the higher the degree of background blur. It is suitable for shooting people, animals, etc.

Precautions for the use of telephoto lenses

1. Due to the long focal length, the camera is prone to shaking, use a tripod and remote shutter to reduce unnecessary shaking.

2. Pay attention to the depth of field, using extreme focal lengths at such close distances can reduce the depth of field to a fraction of a millimeter. Make sure the subject is clear, use a small enough aperture to ensure that the depth of field extends over the entire subject.

3. If you want to capture your subject from front to back, keep it parallel to the sensor. At extreme focal lengths, the depth of field will be so narrow that there may not be more than a few millimeters of depth of field to use.

4. If the telephoto lens has an AF MF switch, switch it to manual focus and manually frame and focus. You may notice that the minimum focusing distance decreases when focusing manually. This means that the subject can be brought closer to the subject, resulting in higher magnification.

5. Use a teleconverter to increase the focal length while maintaining the same minimum focusing distance. This can significantly increase the magnification of the subject without having to move farther.

Why an 85 focal length lens is best for shooting people.

This is because the image distortion formed by the 85 focal length lens is minimal, and of course I want to have better fidelity when shooting portraits, and I don't want to be distorted (in the extreme, a haha lens). The wide-angle lens has the largest lateral deformation (the people on both sides become fat), at this time, it is caused by the requirements for the lens: the requirement is that a graph of evenly spaced graph paper to take out the image requires each square not to be deformed, but the distance between the middle and both sides to the lens is very different, although this goal can be achieved through computer design, but it will inevitably be deformed if it is replaced with a three-dimensional image that is not a plane, so the wide-angle lens is not suitable for taking portraits, only suitable for taking landscape photos that cannot be seen by a little deformation.

Although the lateral distortion of the telescope lens is very small, the longitudinal distortion is very large (the front and rear objects are crowded together), and it is not suitable for portraits, because it is difficult to blur the background to highlight the people, and the dust in the air can affect the clarity of the finished film when shooting from a distance.

The focal length of 50 to 100 has the least distortion, and the 50mm focal length is the most suitable for human vision. The 85 focal lengths between are most suitable for portraits, and the depth of field can be controlled by the aperture, which can be shot, and the portrait is not distorted, the front and back are clear, and the background is very blurry to highlight the artistic effect of the portrait.

Lenses over 400mm are best for photographing birds or wild animals, without disturbing the animals and protecting the photographer from them.

For the full-frame body, 35 must belong to the humanistic lens, 50 must belong to the standard lens, 85 must belong to the portrait lens, and 100 must belong to the "100 micro" lens. are very commonly used. Large-caliber fixed-focus long guns above 400mm are also a weapon for shooting birds.

The full-frame prime lens 50 is the most commonly used focal length, 50mm classic portrait focal length, the angle of view is the same as the human eye, no distortion, and the 35mm focal length is selected for the landscape.

The biggest advantage of the telephoto lens is the framing and composition ability, and the ability to control the local picture is very strong, so it is easy to shoot a good ** with a telephoto lens, such as the 70-200mm lens.

By adjusting the size of the image by zooming, you can get rid of the influence of those cluttered elements on the subject, and you can also zoom in on the subject to achieve the purpose of highlighting the subject. For example, when shooting landscapes, where the scenery is only partial, rather than panorama, using a medium telephoto lens to shoot can zoom in on the local beautiful scenery;

When shooting portraits, in addition to the prime lens, a medium telephoto lens is a better choice, not only to zoom in on the portrait features, but also to shoot portraits from a distance in order to make the person's expression more natural, but also to eliminate the interference of tourists or other elements, which is very practical. Therefore, the telephoto lens brings the convenience of framing: avoid the influence of cluttered elements, zoom in on the subject, and thus make the shot more perfect.

The telephoto lens does a good job of capturing details in distant scenes, and captures some subjects that are not easily accessible. Especially when shooting wild animals, choosing the right telephoto lens can give us a lot of creative opportunities.

Shooting landscapes and people from a distance, shooting stages and sports competitions in the stands, shooting animals in zoos, shooting birds and animals in the wild, adding auxiliary lenses for close-up shooting, etc., in these many fields, telephoto lenses can shoot well. In general, it is best to have the camera fixed on a tripod in order to maintain the stability of the camera.

Telephoto lenses are a great complement to long shots and close-ups – zoom in on long shots, highlight close-ups, and blur backgrounds to accentuate the subject! Generally speaking, the zoom ratio of a small digital camera should not exceed 5x, otherwise the image quality of the telephoto end will be affected.

Telephoto lenses are mainly used for long shots, and due to their relatively small apertures, background blur is good for shooting specific subjects.
