Telephoto lenses work for sports, nature or wildlife photography because they allow you to get much closer to your subject. If you won't be shooting these kinds of subjects, however, the features that make a telephoto lens work for sports and nature photography can work against you, and the lens might actually inhibit your ability to take good pictures.
Depth of Field
Because telephoto lenses have such long focal lengths, often 200 mm or longer, the depth of field you can achieve with them is drastically lower than with a standard or wide-angle lens. This means that only the subject will appear in focus, while most of the foreground and background will be blurry. This low depth of field can make the subject appear isolated in the image and can also compress the space between the foreground and background, making the image look two-dimensional. You might have observed this effect in television coverage of baseball games; the extreme telephoto lenses used to film the pitcher make the distance between the pitcher's mound and the batter look much shorter than the 60 feet 6 inches it actually is.
Perspective
A telephoto lens has a much narrower perspective than both the human eye and other lenses. This narrow perspective drastically limits the amount of a scene or subject you can include in your picture. If you are shooting landscapes, cityscapes, or interiors, this could be frustrating.
Portability
Telephoto lenses are more cumbersome than standard or wide-angle lenses, and carrying them can be difficult while traveling or attending crowded events. Super telephoto lenses can weigh 10 to 12 lbs. (5 to 6 kg). Although you can sometimes support medium telephoto lenses with your hand, super telephoto lenses almost always require steady support of some kind, such as a tripod or a monopod. This support requirement makes spontaneous shooting difficult.
Expense
Telephoto lenses are often much more expensive than standard lenses (up to several hundred dollars more for an entry-level model), giving you one final reason not to buy one unless you want to do sports or nature photography.
