Read moreSigma Fixed Focal Length Lens With innovative, state-of-the art technology, Sigma's complete line of lenses expand your ranges of photographic possibilities. Sigma lenses are designed to be sharp, versatile, ergonomic and unmatched for low weight and compactness. Sigma's fixed focal length lenses range from full macro capabilities to wide and ultra-wide lenses. Some are equipped with a HyperSonic Motor (HSM) for added power and convenience, while still others are ultra-compact to make them lighter and easier to use, especially when shooting on the road. This high-performance tele-macro lens can focus from infinity to full 1:1 life-size reproduction without accessories. At 1:1 reproduction, the distance from subject to film plane is 18.1 , making this lens convenient for photographing subjects that are not easily approached, such as small animals or insects. The apochromatic design and two SLD (Special Low-Dispersion) glass elements, plus the floating inner focus system, effectively control chromatic and spherical aberrations as well as astigmatism, providing superb performance throughout the focusing range. The models for Sigma, Canon and Nikon AF cameras employ Sigma's HSM (Hyper Sonic Motor) for quiet, responsive AF function plus full time manual focus. A Focus Limiter switch aids in faster AF for closer or more distant subject situations, by restiricting the movement of the focusing mechanism. The HSM model lenses can be used with Sigma's 1.4X EX teleconverter as a 252mm f/4.9 lens, with Sigma, Canon and Nikon AF cameras, providing AF function from infinity to about 47 . At closer distances, the lens automatically switches to manual focus. (The models for Minolta and Pentax cameras will be manual focus with the 1.4X EX teleconverter.) This lens can also be used with Sigma's 2X EX teleconverter as a 360mm f/7 lens, for manual focus in all cases. Includes 4 Year Service Plan (1 year international warranty plus 3 years extended warranty).
