Sony's SEL55210 55-210mm f/4.5-6.3 Lens brings the world to owners of NEX cameras in a long telephoto zoom lens. The equivalent of 82-315 mm in full-frame or 35 mm format, this lens has a versatile short-to-long telephoto range. The wide range is great for bringing your subject closer to you, no matter how far away it is. Internal focusing gives you smooth, responsive autofocus, with minimum noise--perfect for capturing video. With a telephoto lens, image stabilization is very important to prevent camera shake--Optical SteadyShot gives you the ability to capture sharp, crisp images (still or video) even in low light or when zooming into distant subjects. Two ED (Extra-low Dispersion) glass elements help to suppress chromatic aberration color bleeding at all focal lengths, so you have excellent image quality throughout the zoom range. This is a lens that you'll want to keep handy at all times for dramatic long-range images.
