Paul, I wonder how the focussing ramp length is influencing the AF speed. In this regard the FA50 has quite a long focussing ramp. I dunno about the 50-135 however but I know my dA18-55 often focussed faster than my FA50/1.4 (!) -- Thibault Massart aka Thibouille ---------------------- Photo: K10D,Z1,SuperA,KX,MX, P30t and KR-10x ;) ...
