Pretty useful long normal to portrait length. Good macro feature at 80mm. Good Bokeh and color. Rather weak in the sharpness and contrast areas. This is on the ist-D, haven't tried it on film. Pretty much agree with Bobs comment on Stans site:
"Bob S. - The reputation on the lens from day one has been weak. . . . I have a copy and it is OK, but not as sharp as the A series zooms." The A 35-70/4 puts it to shame.
