at night, forget about any other focus other than the center point. Anyone else can't find the focal point. with the Canon 7d, I had to use -7 points autofocus adjustment! front focus. Otherwise, the crop matrix has an excellent portraiture, portraits are about to the waist, not very suitable for full height. Some pros: aperture 1.8, fast autofocus, excellent bokeh, seven-bladed aperture, lightweight, inexpensive. Cons: I shoot on APS-C, autofocus smears, there is no guaranteed result, then it will hit, then closer, then further. At aperture 1.8, the edges are terrible, if the photo has a sharp black edge on a white background - this edge will be blurry with a black-purple halo. But on 2.0, the effect is already little noticeable.
