The shortest shooting distance is quite short, and the maximum shooting magnification of 0.5x at the telephoto end is wonderful. Lenses of other companies in this class have a maximum shooting magnification of about 0.2 to 0.3 times, so this proximity performance is likely to be a considerable advantage.
