With improved optical image stabilization performance, this lens system now compensates for 4.5 stops at both minimum and maximum extension, and its newly introduced advanced five-axis sync IS system offers up to 7.0 stops of shutter speed compensation—this is powerful handheld photography. Additionally, with a minimum focusing distance of 4.27' and a 0.57x equivalent maximum magnification this lens maximizes the use of its IS system for an outstanding telemacro performance, opening a world of possibilities when it comes to wildlife photography. Key Features: - When utilizing the MC-20 2x teleconverter, the lens is able to reach up to an impressive 1600mm. - Reliable all-weather durability thanks to its IPX1 rating, dust-resistant design, and fluorine-coated front element. - Advanced optics feature four extra-low dispersion lenses, two super-high refractive index lenses, and two high refractive index lenses. - ZERO (Zuiko Extra-low Reflection Optical) coating minimizes ghosting and flares, ensuring clarity even in challenging backlit conditions.
