Although it is a wide-angle lens, it is possible to take advantage of the bokeh, and when wide open, it gives a soft depiction similar to that of an old lens, but when stopped down one step, the depiction becomes sharper. In addition, the 10 aperture blades create beautiful rays of light from F2.8 to F16. Comes with a 72mm diameter filter holder and can also be used with lens filters. There are two colors: black and silver.
