This super-telephoto zoom lens is truly awe-inspiring — its 150–400 mm range plus a built-in 1.25× teleconverter reaches the equivalent of 300–1000 mm, unlocking extraordinary potential for wildlife, sports, and astro photography. With a constant aperture of f/4.5 and a sophisticated optical design featuring 28 elements in 18 groups (including Super ED, ED, HR, and aspherical lenses), it delivers crisp, high-quality images with minimal aberration. The high-performance stabilization offers up to 8 stops of compensation thanks to synchronized 5-axis IS, while the High‑Speed Imager AF (MSC) autofocus system works swiftly and precisely even at long distances. The minimum focus distance is 1.30 m, and the 95 mm filter thread gives you room to use creative filters. Built from a magnesium alloy body and reinforced with a carbon fiber hood, it’s rugged yet surprisingly balanced — weighing 1,875 g with dimensions of 314 × 115.8 mm. Weather-sealed to IP53 standards and compatible with the Micro Four Thirds mount, it also features a removable tripod collar for stable support during lengthy sessions. Choose this lens to gain a truly professional, high-reach tool that empowers your wildlife, action, and telephoto photography like never before.
