- construction quality, lens hood, built in Japan, in my opinion, good and tenacious autofocus, manual autofocus, iron and glass, The switch on the lens includes two autofocus settings, one for when the subject is close and one for when it is further away. Lovely bokeh. There are no "washers" in the blurry soft plastic. The stunning hue is not white, as seen in the picture; rather, it is slightly gray, yet it looks stunning.
- filters for the "67" thread, regardless of focal length, can be quite pricey.
