Long Lens

Long lens, aka Telephoto is a lens with the focal length of 120mm to 300mm and above. The long lens makes objects appear closer to the camera in a way similar to a binocular. That's why usually your camera will need to be positioned further away from an object when you're using a long lens.

Long lenses tend to have a shallow depth of field - only a small fraction of an image will be in focus. The background will appear blurry.

A long lens will take a longer time to focus and will usually require you to use faster shutter speed. A good rule is to use a shutter speed 1/focal length of the lens. For example, for 600mm lens: shutter speed of at least 1/600. However, you are welcome to experiment, especially if you're using a tripod.

Tip: When shooting a portrait with a long lens (just like any other lens) make sure to focus on the eyes of a person you're photographing. Eyes tend to be the first thing we look at on a photograph and when the depth of field is very shallow you want the eyes to be the sharpest part of an image.
