I once stripped down a F50/1.4 (many years ago) which had 4 electrical straps (or 3?) underneath the focus ring. Looks like for distance data.Yes, you can use P-TTL (and off-flash matrix metering) with ALL Pentax K-mount lenses:

But you compare F100 with MZ5 which uses distant information but has not advanced flash metering. You should compare F100 with MZS. And it must be truth with distant information since when Pentax introduced P-TTL they have not changed anything in lenses!!It proves that it should be similar to Nikon metering.So one can use FA lenses having P-TTL unlike Nikon users who have to buy "D" lens and Minolta ones who have to buy "G" lens.
