You'd be surprised. I have a 28/2.8 AI. Compared to the AIS it is a dog. I also have the 55/3.5 Auto Micro. It is as sharp as the 28/2.8 AIS in the close range, but not sharper. It peaks at 1:10 magnification. There are sharper lenses in the 1:1 to 1:3 range. If you haven't used the lens in question extensively, how can you make assertions about it?
