This telephoto zoom lens covers an extensive zoom range despite its compact size. Two UD optical elements are employed and correct for chromatic aberrations throughout the zoom range. Moreover, a floating focusing mechanism realizes high-quality images at all shooting distances. A rear focus system and ring USM improve autofocusing speed. This lens is also highly rigid and durable overall.
