DSLR Camera Lenses

A telephoto lens has a long reach, allowing you to photograph a subject that is far away or magnifying the subject in your frame. Generally, a lens is considered “telephoto” if it has a focal length of 60mm or longer. Many people confuse telephoto lenses with zoom lenses but they are actually different things.

Telephoto Lenses. A telephoto lens is one designed for photographing distant subjects like wildlife and sports events. They are also used in portrait photography. A telephoto lens is a type of camera lens designed for taking photographs of subjects at moderate to far distances. Telephoto, roughly, means that the lens has a relatively narrow field of view, thus it can be used to look at things further away.

 Telephoto lenses can be either zoom or prime. Zoom means that they can change how far they are looking at or prime means they have a fixed amount of magnification and can't be altered Most photographers will tell you they want a longer-than-normal lens for portrait photography—a short to medium telephoto. On a full-frame DSLR, that translates to lenses with focal lengths typically between 70mm and 200mm. ... One reason why telephoto lenses are preferable to normal and wide-angle lenses is distortion.

Telephoto lenses are incredibly popular among both amateur and professional photographers. They’re useful in a variety of situations and can help you take your photography to the next level. But what is a telephoto lens? A telephoto lens has a long reach, allowing you to photograph a subject that is far away or magnifying the subject in your frame. Generally, a lens is considered “telephoto” if it has a focal length of 60mm or longer.

Many people confuse telephoto lenses with zoom lenses but they are actually different things. A telephoto lens can be—but does not necessarily have to be—a zoom lens. Telephotos come in a variety of focal lengths from “medium telephoto” (generally 70-200mm) and “super telephoto” (longer than 300mm) and they can be either zoom or prime lenses. It doesn’t matter whether the lens zooms—what matters is how long the focal length is.

Telephotos Make Subjects Appear Closer to the Camera

This is the most obvious reason to use a telephoto lens and why most beginners consider getting one. A telephoto lens will allow you to take photos of subjects that are farther away. This comes in handy when you are taking photos of things that you can’t, or don’t want to, get close to. Having more distance between you and your subject can help some people feel more at ease in front of the camera. Taking photos of a soccer game from the sidelines? A telephoto lens will get you closer to the action. Want to take a picture of dangerous wildlife from the safety of your car? A telephoto lens will let you do it.

it can be overwhelming for any beginner to choose their first lens/lenses from the wide variety of choices available for every brand of camera. The simple solution is usually to go for a good walkaround lens that offers a good focal range that suits nearly every type of photography, but once you gain experience and begin to feel the need to expand your gear, you’ll eventually want to consider lenses that offer “extreme” focal lengths.

Both wide-angle and telephoto (or zoom) lenses are invaluable to photographers for offering fields of views that we can’t see with the human eye. Their names are pretty self-explanatory, but once you’ve upgraded to a DSLR or mirrorless camera that gives you a chance to shoot interchangeably with both types of lenses, you’ll realize that they do so much more than offer two different fields of view.

If you’re interested in finding out which type of lens you should add to your gear kit, it helps to learn more about how they work and see the kinds of images they are capable of producing. When used to your advantage, one or both lenses can help you become a more efficient and successful photographer.

As the name suggests, wide-angle lenses offer a wider angle of view of 64° to 180°. Interchangeable wide-angle lenses have shorter focal lengths marked as smaller numbers — 34mm and below, where the field of view starts becoming wider than what “normal” lenses offer.

When shooting wider with an ultra-wide angle or fisheye lens at focal lengths wider than 14mm, the image starts to become distorted at the outside edges of the frame. This type of lens can definitely create unique images, although not all photographers can benefit from using a wide-angle lens due to the distortions that it creates.

As you can see, wide-angle lenses bring in more of the scene, which can be very useful when you want to include more elements into the frame, add context, and provide an environment for your subject.

You’ll also notice that the center of the image looks much further away when shooting from the ground, resulting in an exaggerated perspective that adds depth and gives your viewers more to look at.

How to use wide angle lenses
Capture a table full of food or group shots in confined spaces

1.   Show an entire room for real estate photography
2.  Make images and videos look more immersive (using action cameras with built-in wide angle lenses)
3. Take photos of buildings for outdoor architecture photography  Photograph skyscapes, cityscapes, and wide panoramic landscapes (if you don’t mind the distortion)
4. Conveniently take selfies without getting cropped out
5. Create artistic and abstract images, especially with fisheye lenses
6.   Increase the visual distance between your subject from the background

wide angle images should be like:-
