Got this lens 2nd hand and its in pretty good condition internally. Many people dislikes the donut bokeh effects in the out of focus areas in a shot but I find it pretty good if the background is far away. This is the most lightweight and smallest lens (665g) among the 500mm lenses making it hand holdable, no mono/tri-pod required. It has a minimum focusing distance of 4m and comes with a clear integral filter, as well as an ND4 integral filter.
The only cons about this lens are its fixed aperture at f/8, donut bokeh and some may find it slow in auto-focusing. Hey! it auto-focuses! I would say the focusing speed is comparable to the Minolta AF 100-400mm f/4.5-6.7 APO. Well, lets see some sample shots (EXIF available).

As you can see from the last shot, the donut bokeh is very obvious, much obvious than the rest.
