This is possibly the sharpest lens I have ever shot with. It produces beautiful colour and I loved using it to take portraits on my D70. Really good for portraits and for sport if you can get close enough to the action.
Light weight for its fast 2.8 Aperture, Solid build, Sharp; Even at 2.8, Beautiful Bokeh, Built in hood, Couples well with a tele converter
Sometimes it doesn't seem long enough; ie sports photography, Only really practical for head shot portraits unless you have alot of space to back up; I mainly used it for this anyway
