Hi Nikon Fans, I just came up with a great idea : AFS converter for manual or non AFS lenses - kind of like the TC16-A but called the TC-16AS (with build in ultra sonic motor) It would be fast, silent, and I want one ! I hope Nikon is reading this. Happy shooting, Sover *** News : An F5 was detained by the police for improper exposure - Sover Wong 1998 ***
