All leneses perform best in the middle of their range. On the extremes the image quality suffers considerably, hence why most DoPs try to aim for a 4/5.6 but will shoot if they can from aound a 2.8 to a 8, depending on the lens.
My own Super Speed 9.5mm for example, looks HORRIBLE at a T1.3, and looks mildly ok at a 4, and then looks like my god, what is this at an 11.
