By no means is this technical in any way. I was simply testing for decentered elements by checking all the corners of an infinity shot at 1.4
I was not expecting these results. Simply put an excellent lens.
The photo was taking from behind a window on the 29th floor of my office building. This was just a shot to check corner and edge sharpness. So please don't expect a wonderful image ... Just look at how this lens performs wide open edge to edge
