I think a macro would benefit of it. Usually a macro lens as a long (sometimes very long) focussing ramp (for obvious reasons). In this case, if SSM is supposed to be faster, then yes it would benefit a lot. My SMC 100/3.5 macro which I quite like is difficultto be used as a "normal" lens because of very slow focussing, simply because the time it takes to turn the whole focussing thing is huge.
BTW I find an FA 50/1.4 should benefit of it, it also has quite a long focussing ramp. Thibault Massart aka Thibouille ---------------------- *ist-D,Z1,SuperA,KX,MX, P30t and KR-10x ;) ... -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
