Telephoto lenses are known for their ability to create a shallow depth of field, which is one of their defining characteristics. This effect occurs because telephoto lenses have a longer focal length than standard lenses. As a result, they compress perspective and isolate subjects by blurring the background more effectively. This feature makes them particularly valuable for portrait photography and wildlife photography, where the photographer might want to separate the subject from a busy background and create a visually appealing bokeh effect. In contrast, the other statements do not accurately describe the capabilities and characteristics of telephoto lenses. Some telephoto lenses can work effectively in various lighting conditions, and while some of them may be lightweight, many are not. Additionally, telephoto lenses can indeed affect movement capture; subjects at varying distances from the camera may appear compressed or distorted due to the lens's properties, and faster shutter speeds are sometimes required to avoid motion blur with longer focal lengths. Understanding these aspects helps photographers choose the right lens for their specific needs and desired outcomes in their imagery.
