This is a telephoto zoom lens with excellent cost performance, for it is capableof macro photography with a 1:2 maximum close-up magnification at the 300 mm focal length. It also has a switch for changeover to macro photography at focal lengths between 200 mm and 300 mm. The minimum focusing distance is 1.5 m/59 inches at all zoom settings. We used SLD (Special Low Dispersion) glass in this lens for excellent correction of chromatic aberration. And, we effectively corrected for fluctuation of aberration due to focusing. It is the ideal lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range.
