compared to:
price paid:
positive:Fast accurate focus
Surprisingly sharp
Depth-of-field scale
Stiff but exact zoom ring
Among the lightest in this range
negative:MF/AF manual clutch in addition to the camera's switch
Some flaring
Maybe a bit softer wide open
comment:This is now my everyday lens on my 5D, I got it in excellent condition second hand. I have shot some beautiful available light pictures with it, and having a constant f/2.8 also makes the viewfinder wonderfully bright under low light conditions.

I got it cheap, and have seen it sold quite cheaply, which makes it a real bargain. Grab one if you can!
