I bought Tokina 100mm AT-X Pro f/2.8 Macro based on positive reviews and the price. After shooting few times with the lens I can say the lens is really sharp and it is not just "sharp for its price", but sharp regardless of the price. AF is bit slow so this is not for sports, but who would use 100mm lens for sports anyhow. For portraits and macro this is a great lens. Strongly recommended!
