Well... during the years I have adjusted the focus on my RB 67 (pro SD) my hand did NOT touch the lens.... since the focus is adjusted by turning the knob on the RH side of the body...and that knob is turned 'clockwise' (looking from the RH side of the body) to focus 'closer' (ie.it extends the built-in bellows). The nly time I 'touch' the lens (per se) is to select the f-stop.

After all, I got my first Nikon F way back in 1967.
