With a focal length equivalent to that of a 27.5-83.0mm zoom lens in 35mm format, this lens is ideal for wide to medium telephoto applications where zooming flexibility is required. Incorporating four extra-low-dispersion and low-refractive index aspherical optical elements in its optics, it assures exceptional image rendition while effectively reducing chromatic aberration to a minimum over the entire zoom range. It offers a minimum focusing distance of 30cm at all focal lengths to simplify close-up photography. Lens shutter features 5 aperture blades and syncs with the Q’s built in flash at speeds up to 1/2000 sec. Neutral Density filter allows for open aperture photography in bright settings.
