The Micro Four Thirds Leica DG Vario-Elmar 100-400mm f/4-6.3 II ASPH. POWER O.I.S. Lens from Panasonic features the ability to expand the zoom range when paired with the optional 1.4x and 2x teleconverters while shaving off more than a centimeter of length for a more compact form factor. The lens now offers macro capabilities, with a full-frame equivalent magnification of .5x that is expandable to 1x with the optional 2x teleconverter. It is Designed in collaboration with Leica according to the company's strict quality standards, the lens has an optimally arranged structure featuring one aspherical lens, two extra-low dispersion lenses, and one ultra extra-low dispersion lens to deliver clarity, sharpness, and color accuracy throughout the entirety of the zoom range and across all edges of the photo. The POWER O.I.S. system also benefits image sharpness, minimizing the appearance of camera shake when shooting at longer focal lengths with its compatibility with Lumix G cameras' Dual I.S. function. The on-body Zoom Limit Switch allows you to quickly constrain the zooming range of the lens to allow for improved autofocus performance and prevent over- and under-magnification. Its rounded nine-blade diaphragm contributes to a pleasing bokeh quality when working with selective focus and shallow depth of field techniques. While its lightweight, compact form factor is suitable for handheld shooting, the 100-400mm f/4-6.3 also features a removable rotating tripod collar for fast switching between horizontal and vertical shooting orientations when working atop a monopod or tripod. The body's gapless construction that renders it dust- and moisture-resistant has an added level of freeze resistance, expanding the lens' field-readiness.
