Manufacturer's Description
With the standard lenses, focus is set to AF, meaning you must switch from AF to MF to use the manual focus mode. However, with the convenient Quick-Shift Focus System featured in the Samsung 16-45mm lens, you do not need to change settings and instead can focus on capturing your image. The short f4 focal length enables you to set the focus even at a distance of 0.24m from the subject. The 10/13 lenses, consisting of an Extraordinary Low Dispersion lens and two Aspherical lenses, offer high optical efficiency.
