I'm getting sick of all these AF techno babble. Thinking of selling my AF gear to fund the purchase of a Nikon MF system (with AF Nikkors just in case, but I'll get some AIS ones too), most likely the FM3a. I'll also get a light meter to complement the camera. Has anyone done that before, as in, go back to the "basics"? If so, what particular aspect of the current AF generation do you miss the most (besides AF that is)?
