You need to try the FA 100mm f/2.8 macro. 270 degrees gets you from infinity to 1:1. With the focus limiter on it stops after about 45 degrees (about 2ft. focus distance). The gearing from the AF screw to the barrel doesn't seem to be any different to any other lens and as a result it's the quickest AF lens I have.
