What is a telephoto camera?

Question 1: What does a telephoto camera mean? A telephoto digital camera refers to a model with a large optical zoom factor. The larger the optical zoom factor, the farther the scene is photographed.

The main feature of telephoto digital camera is actually similar to the principle of telescope, which changes the focal length through the movement of the lens inside the lens. The benefits of telephoto come into play when we shoot distant scenery or photographers don't want to be disturbed. In addition, the longer the focal length, the shallower the depth of field, which is the same as the larger the aperture. The advantage of shallow depth of field is to highlight the subject and blur the background. I believe that many fans pursue shallow depth of field effect when taking photos, making the photos more professional.

Question 2: How does a telephoto camera take pictures? You fainted when they copied it. Let me give you a brief introduction. The telephoto lens is actually the same as the card machine, except that its machine is large, and its optical zoom is larger than that of the card machine, which is generally 15 to 30 times. As for imaging, it's the same as the card machine. If you want to get a good image, you must buy the classification of SLR cameras: card machine, which is the thin digital camera that everyone usually buys. Telephoto machine: The lens is large and the body is a bit like a SLR camera. The same point as the card machine is that the camera speed is as slow. Just press the card and you can take pictures. The difference is that the optical zoom of telephoto lens is relatively large, 10 to 30 times, such as Fuji's S4050, HS 1 1 HS22. Next, I'll introduce you to SLR cameras, which are 3500 to tens of thousands on the telephoto machine. The difference between a SLR and a card-type telephoto lens is that its lens can be replaced, and he can use the money to buy a camera that can be used as a telescope. To put it bluntly, he can shoot birds or animals far away, and even the police and paparazzi regard him as a spy. Another feature of him is that the speed of taking pictures at once is several times faster than the first two cameras. Moreover, its camera sound is very mechanical and crisp, and the first two are the camera sounds made by speakers. Another advantage is that taking pictures is much clearer than the first two. The best is a full SLR camera, 15 thousand to more than 200 thousand. Anyone who mixes this meal will buy such a camera. Ordinary students or posers suggest buying a SLR of more than 5,000 yuan, which is enough to pull, such as Canon's 550d60. Either on the better 7D or on the Pentax K5, the price is 12000. No matter how high it is, it is a full SLR, which is extravagant. Personally, it is not recommended to buy a SLR below 5000 ~ if you have no money to buy a SLR, you can buy a Fuji S4050, which is also a telephoto. If you buy an expensive HS22, you might as well save some money and buy a SLR 600D ~ otherwise you will regret it ~

Question 3: What does the telephoto in the camera mean? A telephoto is like a telescope.

Question 4: Camera type: SLR, telephoto, what do you mean? What is the difference? From the perspective of camera types, SLR cameras are the general name of interchangeable lens single-lens reflective viewfinder cameras, which are characterized by viewfinder framing and interchangeable lenses. The telephoto camera is a simplified version of SLR, that is, the lens cannot be replaced, and the focal length extends from the wide-angle end to a large zoom range above 100MM focal length.

From the perspective of lens differences, telephoto can also refer to the differences of SLR lenses. For example, SLR lenses can be divided into fixed-focus lenses, such as 50MM fixed-focus lenses, 85MM fixed-focus lenses, 100, 200, 300, 400, 500, 600 and other fixed-focus lenses. Zoom lenses, such as 18-55 lens, 24-70 lens and 70-200 lens, are all zoom lenses. It can also be distinguished according to different focal lengths, such as wide-angle lens, ultra-wide-angle lens, medium-focus lens, telephoto lens and ultra-telephoto lens.

Question 5: Advantages and disadvantages of telephoto cameras 20 15 telephoto cameras should be defined as non-replaceable lenses in consumer cameras with high zoom ratio (maximum focus/minimum focus).

The most direct advantages are cheapness, portability and small size. Because of the high zoom ratio, it can be suitable for most daily shooting needs (wide angle to medium telephoto).

Disadvantages: not as light as cards, not as high as SLR.

Card machine has nothing to say. Let's analyze the difference between it and SLR.

First of all, the lens, usually the focal length is less than 3 times better than the zoom lens, such as 24-70, 70-200. The high focal length ratio of telephoto camera determines the quality of lens. Fixed-focus lenses are usually better than zoom lenses, while telephoto cameras are worse. Lens differences are reflected in color and wide-angle edge distortion.

Let's talk about imaging chips first. Because of the size, the imaging chip of telephoto camera is not too big, which is similar to the card machine. Then the area of the imaging chip determines the fineness of the photo. This factor determines that the 1500W pixel SLR is much better than the 2000W pixel mobile phone photo. And pixels are not compensated by the algorithm.

To sum up, if you don't have high requirements for image quality and color, you can use a telephoto camera, which is economical and practical.

If you need high color accuracy and good control of image edge distortion, and you need to output photos with large size and fine image quality later, then you can get a SLR. Prepare more money to buy lenses.

However, I have to say that the current SLR seems to be unable to improve. Many people go out to play and are using automatic SLR. So I think it's good to use a telephoto camera if you travel across mountains and rivers. If it is a SLR, there are 4 or 5 lenses on the back. If it's a man, it's okay. If it's a woman, I'm afraid I'm not interested in playing.

Question 6: What are the disadvantages of telephoto cameras? Digital Cameras For these super-large zoom digital cameras with 10 times optical zoom lens, some overall defects will have a fatal impact on the final shooting quality and the use of users. 1, the telephoto end focuses slowly. As we all know, the autofocus technology of consumer digital cameras is not very advanced, and it is not ideal in terms of speed. This is why many people use consumer digital cameras for a while and then switch to digital DSLR. For these 10 zoom machines, the autofocus at the telephoto end will be tested even more. Judging from these machines currently on the market, many machines do have defects in this respect. Mainly manifested in the focus is uncertain, or unable to focus, which is especially obvious in dark places. 2. Shake when holding. Most friends who are familiar with photography know the concept of safe shutter speed. The safety shutter speed is actually the reciprocal of the focal length. The so-called safety means that if the shutter speed you use is higher than the safe shutter speed, the photos you take will not be blurred because of uncontrolled shaking of your hands. On the contrary, if it is lower than this speed, it will be more dangerous. Because the focal length of a digital camera with 10 times optical zoom is very large, we are required to ensure a high shutter speed when shooting. Otherwise, it is easier to lose precious wonderful pictures. 3. Image quality. We have actually talked about this problem above. As far as the ultra-large zoom digital camera that has just been listed at present is concerned, its image quality is not strictly a good category, especially the telephoto end. 4. Weight and volume. With more and more lenses used in digital camera lenses with zoom 10 times, the aperture and volume of the lens will also become larger, resulting in a corresponding increase in the volume and weight of the camera. Although there are some ultra-zoom digital cameras with compact design, so far, there is no ultra-zoom digital camera weighing less than 200 grams.

Question 7: Let's not talk about the differences between telephoto cameras and SLR cameras.

Let's start with your D5000. You just bought a condom 18-55, and the focal length is very limited. The biggest advantage of being a SLR is that you can change the lens. So if you think the focal length is not enough, buy a telephoto lens, such as 70-300. If the original factory head is too expensive, buy a deputy factory head, such as Longteng's 70-300 with anti-shake macro 1000 yuan.

You can zoom in on distant objects with a 70-300mm lens.

So your model suits you, but you need to buy another telephoto lens.

Let's talk about telephoto cameras. The so-called telephoto camera generally refers to the long focal length of ordinary consumer models. For example, Fuji S8 100, 35mm equivalent focal length is 27-486mm. The maximum focal length is 486mm, which is definitely farther than your18-55 mm.

But after you buy a 70-300 telephoto lens, your focal length can be converted according to the ratio of 1.5 times, and it can reach 105-450mm, which is basically comparable to him. What's more, you use a SLR, its CCD is relatively large, and the imaging quality is definitely much better than S8 100.

In the vice factory, there are only two suitable supervisors, Sima and Longteng. Longteng is a little more expensive, which is only a matter of one or two hundred. Besides, more than a thousand people are basically poor, and people with high prices can do a good job, but prices have gone up.

Question 8: What is the difference between a telephoto camera and a SLR camera? Correct the above. Not all SLR cameras can be used as professional cameras, and even 5d2 can only be regarded as professional cameras. Ordinary SLR only allows users to use various lenses flexibly according to their own wishes and create their own works, which is also the purpose of ordinary people playing SLR.

Satisfied, please adopt.

Question 9: What are telephoto cameras and SLR cameras? A telephoto digital camera is a digital camera with a telephoto lens, and a SLR digital camera refers to a single-lens reflective digital camera. The main difference between them is the imaging technology and the CCD size difference.

I suggest you use a telephoto camera: Fuji S 100FS is a very out-of-focus machine, especially in color and noise control, with a unique film simulation. Canon's color performance is warm, Nikon's is cold, mainly depending on your personal preference.

Choosing a camera is to read more evaluation articles and information reflected by users and have a comprehensive understanding of the camera.

I suggest you choose Fuji S 100FS.

Question 10: What is a telephoto camera? What is the main purpose of using it? A telephoto digital camera refers to a model with a large optical zoom factor. The larger the optical zoom factor, the farther the scene is photographed. Representative models include Minolta Z series, Panasonic FX series, Fuji S series and Kodak DX series. In some digital cameras, the longer the lens, the larger the moving space of the internal lens and the photoreceptor, and the larger the zoom factor.

The role of telephoto

Take a long shot first to make the distant scenery clearer.

The second is to make the whole picture smaller and the main body bigger. Let people focus on the theme you want to express.

The third is to compress the depth of field, just like the characteristics of some characters, only the face is clear, and the northern scene is all blurred, which requires the cooperation of telephoto lens and large aperture.

Although popular, please note that the longer the focal length of the lens, the easier it is to blur the photo. Usually telephoto lenses should be used with tripods.
