High zoom ratio
Mounted on a PENTAX digital SLR camera body, this zoom lens offers approximate 14X zoom ratio that covers the range from 27.5mm wide angle to 383mm super-telephoto in the 35mm format. Without the need for lens changes, it can be used for a wide variety of applications — ranging from such standard applications as landscape photography, snapshots and portrait at frequently used focal lengths, to specialized applications like sports and wildlife photography at the super-telephoto range.
Superb image description assured by extra-low dispersion (ED) and aspherical optical (AL) elements
Incorporating two extra-low dispersion (ED) elements and two aspherical (AL) elements, this lens effectively compensates for the adverse effects of various aberrations, assuring outstanding image description.
Digital SLR exclusive design
This lens is exclusively designed for use with PENTAX digital SLR cameras, with its image circle perfectly proportioned to their image sensor size (23.5mm x 15.7mm). Since the coating, curvature and position of all optical elements are optimized for the characteristics of digital images, the lens effectively minimizes annoying flare and ghost images in the resulting images.
Minimum focusing distance
An extra-short minimum focusing distance of 0.45 meters over the entire zoom range
Inner-focus (IF) mechanism to avoid lens extension during focusing.
