How far can a telephoto lens shoot?

Question 1: How far can a SLR telephoto lens shoot? It depends on how long the lens is used and how far the object is shot. Any lens can shoot things far away, even the moon.

landlord, do you mean how clear the lens can be when it pulls in a distant object? It depends on your focal length. For example, if you shoot something 5 meters away with two lenses with a maximum focal length of 4 and 2, it must be 4 shots clear. If you want to shoot a big moon, you have to add a magnifying mirror to achieve it.

Let me give you another simple example. The two lenses of Canon's 18-55 and 18-135, one can zoom in three times (55/18), and the other can zoom in seven times (135/18). If you shoot something at the same distance, you will definitely get a clear shot of the 18-135 lens after magnification.

But the landlord should also pay attention to the fact that the greater the focal length multiple, the worse the imaging quality.

I hope I can help you with all the above. If you have any questions, you can ask me online.

Question 2: What methods can be used to increase the shooting distance of telephoto lenses? If you mean "you can shoot the same picture when standing at a farther place", there are two ways:

One is to change a lens with a larger focal length; The other is to install a range finder between the lens and the fuselage, which is 1.4 times or 2 times. After installation, your focal length will be 1.4 times or 2 times (which will reduce some image quality).

question 3: actually, you are caught in a wrong concept about how far a SLR lens can shoot.

zooming is not necessarily farther than taking a big picture.

according to the equivalent focal length of the multi-element lens.

the zoom ratio of a lens, that is, several times zoom, depends on the ratio of the maximum focal length to the minimum focal length.

for example, 18-55 is 55/18=3, and this is about 3 times the zoom lens. Another lens is 5-1, which is a double zoom lens, and another lens is 2-3, which is a 15 times zoom lens.

so which one do you think is farther? In fact, that zoom is farther than the smallest 5-1 photo. Why? Because where is the focal length?

so, to put it bluntly, which shot is far in the end depends on the equivalent focal length. On the contrary, which photo is wide depends on the equivalent focal length.

general DC will indicate the equivalent focal length.

in terms of SLR

the conversion coefficient of an aps-c machine like Canon's 5D 55D is 1.6

that of Canon's 1D aps-h machine is 1.3

that of Nikon's aps machine is 1.5

that of Olympus is 2

that of Equus is 1.7

So, If a 2mm lens is

, then on Canon aps-c, Equivalent to 32mm

equivalent to 26mm on Canon aps-h

equivalent to 3mm on Nikon aps

equivalent to 4mm on Olympus

equivalent to 34mm on Sima's machine

equivalent to 2mm on any machine in Quan Huafu

Although it is the same lens, you can see that the equivalent focal lengths of lenses with the same focal length on different frames are different.

so you should be able to understand?

Question 4: There is no such statement as how many meters a telephoto lens can shoot at the longest distance for a SLR camera. The principle of telephoto lens is similar to that of a telescope, and there is no such statement as how many meters can be shot at the longest distance.

Question 5: How can a telephoto lens increase the shooting distance? This is related to the size of the object being shot. For example, if you want to shoot a house 1-15 meters away, a focal length of 2-3mm is enough. If the car is 1 meters away, it may have to use 4-5 mm; If it is a small animal or a bird, then it may not be enough to use 5-6, and it is only necessary to add a range finder. Therefore, please add your specific subject matter.

hello. From your supplement, it seems that the subject to be photographed is relatively small, and it may be really difficult if it must be 1-15 meters away. If possible, you can consider using a telephoto lens of 6-8mm plus a 1.4 or 2 times range finder, but the price is very expensive. Really not, you can look at the catadioptric lens in the second-hand market, and you can buy the extra long focal length you need at a relatively approachable price.

question 6: what specifications of telephoto lens do you need to shoot the details of an object at a distance of 1m? This is still related to the size of the object being photographed. For example, if you want to photograph a house 1-15 meters away, a focal length of 2-3mm is enough. If the car is 1 meters away, it may be 4-5 mm; If it is a small animal or a bird, then it may not be enough to use 5-6, and it is only necessary to add a range finder. Therefore, please add your specific subject matter.

question 7: how many meters can a telephoto lens for a SLR camera shoot at the longest distance? Super telephoto lens can shoot a full frame of the moon. If it is 8mm, it can shoot a water cup 1 meters away into a full frame. How far can it shoot? If the air is clean, 1 kilometers is no problem. < P > Question 8: Can a SLR buy a medium telephoto lens to shoot at close range? You have asked a lot of questions, but it can be seen that you really need to figure it out before buying a camera. Each lens has a closest focus distance, which is basically infinite if it is far away, but the telephoto lens can shoot the distant scene larger than the wide-angle lens. Generally, if you want to learn photography, you should buy a SLR. The Internet is indeed much cheaper than a physical store. There is no fake camera, but you should pay attention to repairing the machine. As for whether to change the lens often, it depends on the actual situation.

Question 9: How far can a telephoto lens shoot? The telephoto segment is called telephoto, and generally it can shoot a portrait of more than ten meters. Flowers are all good, but it is poor to shoot birds. More than 2 people are called super telephoto, and the big birds are all 4,6 or even 8 telephoto shots, but the ones that are really far away are actually super telephoto.
