telephoto

A telephoto lens is a long-focus lens used to capture distant subjects. It is commonly used in sports, wildlife, and nature photography. Telephoto lenses magnify the subject, making it appear closer than it actually is. They are also used to create a shallow depth of field, which can help isolate the subject from the background.

Telephoto lenses come in a variety of focal lengths, from 70mm to 600mm or more. The longer the focal length, the more the subject will be magnified. Telephoto lenses can be used on both full-frame and crop-sensor cameras. However, the effective focal length of a telephoto lens will be different on a crop-sensor camera than on a full-frame camera. For example, a 100mm telephoto lens will have an effective focal length of 150mm on a crop-sensor camera.

Telephoto lenses are a type of long-focus lens that is used to capture distant subjects. They are often used in sports photography, wildlife photography, and portraiture. Telephoto lenses can be either prime lenses or zoom lenses. Prime lenses have a fixed focal length, while zoom lenses have a variable focal length.

When choosing a telephoto lens, there are a few things to consider. The first is the focal length. The focal length of a lens is measured in millimeters, and it determines the angle of view of the lens. A shorter focal length lens will have a wider angle of view, while a longer focal length lens will have a narrower angle of view.
