When speaking of Nikon/Canon I was thinking more of modern entry levels like D350, D50 and D70. That's the bodies the K100D And K110D are up against, not old film bodies.
Next generation Pentax entry level will be up against D400 and D80. If Pentax want to match Nikon and Canon on AF speed they need to have USM or similar feature enabled, IMO.

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 PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
