All Canon EF mount bodies except the extremely rare EF-M MF body support USM, as they all use in-lens AF motors and USM motors are just a couple of variants of that (Canon has at least 3 different types of USM implementations). All Nikon digitals support AF-S/AF-I lenses (Nikon's USM[AF-S] and in-lens motor[AF-I] names). For the film bodies, it's more complicated, but none of the base model AF bodies (F55/50, F401's) support it. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
