The sample pictures were shot on Sony Nex 5 Camera via an adapter, APS-C sensor, on a larger sensor the effect will be more pronounced. Shot wide open and at F4.
As you close down the aperture the effect is reduced, closed to the extreme, F11 and on it almost goes away.
The lens is lite, comfortable to use, all metal and glass construction, extremely well perserved.
