Lens Reviews:

While the lens is just slightly soft at ƒ/1.8, but when stopped down to ƒ/2.8 it provides sharp images indeed. Chromatic aberration is very well-handled, though when used wide open there is a bit of corner shading. Distortion is also very slightly noticeable. Only it could be better if it were full-frame compatible.
