Photographers love telephoto lenses. We can’t always get close to the subjects we want to shoot, and a telephoto lens allows us to fill a significant part of the frame with them. That makes a picture with a lot of visual impact.
-Reflecting telephoto lens. The overall physical length of a telephoto lens is usually only about one half of its focal length.
Telephoto Lens
A lens that makes a subject appear larger on film than does a normal lens at the same camera-to-subject distance.
Telephoto Lens
A Telephoto Lens has a long and fixed focal length (100-800mm). These long lenses enable you to compress a distance (and compress the sense of depth, as well) and pick out specific objects from far off.
Telephoto lenses have focal lengths that range from about 85mm (great for portraits) to super-telephoto lenses of 300mm-600mm (lenses in this range are often used by sports and wildlife photographers).
Telephoto Lens A specific type of long-focus lens in which a positive (converging) lens element is placed in front of the diaphragm and a negative (diverging) lens element is placed at the rear of the diaphragm.

Through-the-lens meter (TTL meter). An exposure meter built into the camera that takes light readings through the lens.
Telephoto Lens: Lenses whose focal lengths are longer than 50mm (in 35mm photography). Telephoto lenses enlarge the subject size.
TELEPHOTO LENS- You can think of telephoto as the opposite of wide angle. This is the range from about 55mm and above. Film cameras can have lenses that range up to and above 1,000mm. With digital cameras, most only go to about 115mm.
Telephoto lens. A lens or lens setting that magnifies an image.
Test strip. One of a series of test exposures on a piece of printing paper, then processed to see which gives the most satisfactory result.
TELEPHOTO LENS - A lens with a narrow angle of view, a longer-than-normal focal length, the ability to magnify images, and exhibiting relatively shallow depth of field.
Best Telephoto lens for sports photography
The DSLR lens you choose to purchase for your sports photography needs, will also need to be a telephoto lens. How long of a telephoto lens, will depend on what your intending to shoot.

With the wide lens, you've explored the possibilities in showing a subject plus its environment. With the telephoto lens, you must learn to find good compositions where you isolate your subject from its environment.
Telephoto lenses are those with focal lengths over around 85mm. They are used to pull in far away objects and photograph subjects you can't physically get close to, whether that is a wild animal or the top of a mountain.
Telephoto lenses compress the visual space, causing foreground and background elements to appear closer together. In contrast, wide-angle lenses stretch the visual space.

The telephoto lens has the reversed characteristics: all elements of the landscape are pushed against each other so to speak - the image suggests distance rather than width. The perspective is compressed.
Telephoto lenses - are great at taking portraits and close-ups.
Wide-angle lenses - as the name implies, they are wider and great for landscapes and indoor photography such as taking a photo of a room.
Telephoto lenses and close up lenses and flash equipment form a part of certain trick effects one wishes to create.
Telephoto lenses are also useful, although the narrow field-of-view makes it difficult to capture the sense of space. Also focusing must be precise, especially with large apertures.
Telephoto lenses are limited to 135 mm or shorter (coincident rangefinder cameras)

"using a telephoto lens (anything above 50mm) won't push the background away-it'll bring it closer. Telephoto lenses compress the depth of the image; wide angle lenses expand the depth of the image." ...

Inverted telephoto lens
Lens constructed so that the back focus (distance from rear of lens to film) is greater than the focal length of the lens. This construction allows room for mirror movement when short focus lenses are fitted to SLR cameras.
When you use a telephoto lens, the need for support form underneath becomes more urgent. Not only because the weight distribution is now tipping the camera forward but also because the narrower angle of view will accentuate any camera shake.
What about long telephoto lenses? Well, they do tend to "flatten" the subject somewhat, but it's not really a very noticeable effect.
When using a telephoto lens it becomes apparent that a tripod is a must since at a zoom of 200mm or more there will be movement which will get registered when you take a picture.
SAME FOV WITH TELEPHOTO LENSES
In the image series below we moved our tripod and 180 lens until we had the same field of view for all three photos.
Zoom lenses - telephoto lenses
These lenses let you zoom in on your object and take pictures from a great distance thanks to the focal length range they come in, for example 70-300 and 55-200.
Obviously, if a telephoto lens compresses depth, a wider-angle lens stretches depth. When we speak of changes in depth, we mean all depth, not just big foreground/background changes. This is important to remember when shooting portraits.
