A 160mm lens is a type of camera lens that has a focal length of 160 millimeters. This longer focal length allows photographers to capture distant subjects with greater detail and clarity. It is commonly used in portrait photography, wildlife photography, and sports photography, where getting close to the subject may not be possible. This lens can be either a prime lens, which has a fixed focal length, or a zoom lens that offers a range of focal lengths. The aperture of the lens also plays a crucial role in determining how much light enters the camera, affecting the overall exposure and depth of field in the images.
