The E 55-210mm f/4.5-6.3 OSS is a budget-friendly telephoto zoom, ideal for photographers who want to try out a longer focal length range without investing in a heavy and expensive lens. With an APS-C equivalent range of 82.5-315mm, this lens works best when capturing wildlife, sports, and other outdoor activities that require a distance between you and your subject. Optically, this lens incorporates two extra low dispersion elements and two aspherical elements, which combat a variety of aberrations and distortions. Optical Steady Shot image stabilization helps reduce camera shake when shooting handheld, and AF is quick and quite due to an internal focusing mechanism.
