I bought this lens around 2004 ~ 5 at the time I still had my Nikkormat camera which I acquired in HK in early 1980’s. I thought that the camera would still function when I retired in 2009; I was wrong. Then I acquired Nikon D300 and later D300s. I used the later this afternoon; I found its weight a bit heavy when used in manual mode. I like the bokeh of the lens albeit sharpness is ok. The last 15 photos (mostly portraits) were taken on the next day with the circular polarizer removed, and with the Nikon D300 replaced by a Pentax K-3 camera (which issues a beep sound whenever the subject is in focus, rendering focusing a lot easier than that of Nikon) .
