Overall and wide open, my sharpest lens is undoubtedly the DA* 60-250/4. if restricted to one stop, my k 85/1.8 might well be the sharpest, probably at f 5.6. My K 28/3.5 was amazingly sharp at f 5.6 and f8, but I no longer own that lens. I have several FA lenses. I don't find any of them to be remarkably sharp.
