An excellent lens if used for its intended purpose (portrait, product photography, even landscape). It behaves very well on inexpensive cameras like D40x. Different pros: A very pleasant and high-quality image (a combination of sharpness over the entire area of ββββthe frame, contrast, color and very pleasant bokeh). The appearance is very solid (but not tired) with a small weight and acceptable dimensions. Got cons: "Macro" at an average level (chromatic oberations are visible, a slight drop in sharpness), although the lens is not intended for this
