An 8x zoom range starting at an uncommonly wide 50mm and half-life-size macro magnification at 9.8 inches set this lens apart from traditional 100-400mm telephotos. The VXD linear motor delivers fast, silent autofocus, while the 1152g build and 67mm filter thread keep it portable for a full-frame super-telephoto. This lens is best for wildlife and travel photographers who need a single, weather-sealed solution to capture both environmental context and distant details without switching lenses.
