Offering remarkable reach in a somewhat compact design, the X-mount 100-400mm f/5-6.3 DG DN OS Contemporary lens, is an adaptable telephoto zoom mixing a hand-holdable design with apt optical performance. A series of low dispersion glass elements are utilized to attain high clarity and color precision throughout the zoom range, and to suppress chromatic aberrations and color fringing. Accompanying the optics is intuitive handling, in which a stepping motor delivers quick, near silent autofocus performance along with fine-tuned manual focus control. Furthermore, four stop-effective optical image stabilization helps to diminish the appearance of camera shake for sharper handheld shooting and this 100-400mm is also compatible with the optional TS-111 Tripod Socket for steady shooting atop a tripod or monopod.
