Just to clarify, Pentax is the same as Nikon, both focus and f-stop. I started with Fujica ST (also the same), went to Nikon, then to Pentax, then to Bronica, (same, plus lenses mount the same direction as Nikon). I still have all four makes. After 39 years, I suppose I'd go nuts trying to adjust to a Canon, Minolta, etc, now.

I do have two lenses which focus opposite: a 17mm Tokina in Pentax mount (would it have killed them to have made reverse helicoids for their Pentax and Nikon mounts?), and a Tamron Adaptall 500mm mirror. I always start the wrong way and have to correct myself.
