Bokeh has a fickle character, plastic, but generally quite nervous, with impulsive strokes that can be more disturbing or more calm, soft, but not without some dynamism - depending on the degree of diaphragm closure. At 1.8 blurs the background well. Thus, the photographer gets a rather powerful, if skillfully used, expressive tool that can emphasize the idea of the frame (if any). Thoughtless use of the lens, especially in inappropriate scenes, can be frustrating and irritating. Due to its price and wide presence on the market, this artistic tool is a reliable tool at hand for a photographer who has taste and own vision. The most expressive use can be on an open aperture. They write that AF-S 50mm 1.8 G is a version of this lens, only with an ultrasonic motor. In fact, this is not the case - there are differences in the optical design, an additional aspherical element has been added to the rear lens group, which improves the picture of sharpness. There is also a smoother blur, but the range of expressive possibilities of the lens as an artistic tool, in my opinion, is significantly reduced.
