Yes I know the difference. I think anybody else investigating the purchase of such a flash would, too. If I want to have true wireless, and lose the option of P-TTL, I'll use my FlashWaves radio triggers to fire the Metz and/or Pentax flash.
My Sunpak 383's work fine on radio triggers but can't do P-TTL. The Metz can do both. Again, if anybody's interested there are rebates now available.
