Internal zooming maintains constant balance across the 180-600mm range, aided by 5.5-stop VR and STM autofocus for steady handheld shooting. The zoom ring reaches 600mm in just a 70° turn and close-focuses to 4.27 feet (0.25x magnification), while compatibility with Z teleconverters extends reach to 1200mm. This lens suits wildlife and sports photographers who need a durable, weather-sealed super-telephoto for quick framing and long-range tracking without a tripod.
