This refers to a specific type of photographic lens. The “35mm” indicates its focal length, a measurement that influences the angle of view and magnification. “f/1.4” represents its maximum aperture, defining the lens’s light-gathering capability and ability to create shallow depth of field. “AIS” denotes a particular focusing system from a specific manufacturer, Nikon, indicating compatibility with certain camera bodies.
Such a lens is valued for its versatility in various photographic genres, including street photography, environmental portraits, and landscape work. The wide aperture allows for shooting in low-light conditions and enables the creation of images with blurred backgrounds, isolating the subject. The specific focusing system ensures manual control and a tactile shooting experience favored by many photographers.
