Fujinon HK Premier Zoom 14.5-45mm T2.0 covers unlimited focal lengths in a range where primes previously were the rule. This lens works like a high-end Prime when dealing with distortion, chromatic aberration, and all the tough challenges of wide angle lens design. MTF and resolution is stellar from the center to the corners, without shading or fall-off. The Fujinon Premier 14.5-45mm is the most compact of the four Premiers.
