Great value for the money!
Fast lens. Great value. Fairly lightweight.
Slow focus. Clunky mechanism. Push pull zoom.
F-stop is great for a telephoto. The 1.6x magnification for digital EOS systems gives you a 320mm with an f4. For this price, nothing can touch it! Not very fast in the autofocus department. Found that I would need to switch to manual focus most of the time for sports. Excellent...
