Query: tack sharp without "L" prices

This lens is legendary. If you are after tack-sharp portraits with beautiful saturation and color, beautiful bokeh, and are on a limited budget, get this lens. It's fast, sharp, and relatively inexpensive.Definitely invest in the ET-65III hood, too. Consider it a required accessory of you don't like flare.I am using the lens on a crop body (Xti) so the effective focal length is about 135mm. This is a little long for much beside portraits, and too short for nature or outdoor sports. It might serve well in indoor sports, however.Another "portrait" lens you might consider if on a budget and using a crop body is the 50mm/f.18. It doesn't look sexy on the camera, but at $70 you can't go wrong and the IQ is really astonishing for the price.
