I would add it's a matter of supply. The F series lenses had a short production life. The original autofocus SF1 or SFX were not popular. Pentax was a bit behind the marketplace here (slow AF & noisey). The next generation PZ-1 camera series saw the introduction of the FA series lenses and lasted a lot longer. So I expect the number of F50/1.4 lens produced is much lower than the FA50/1.4 production. I am lucky to have an F50/1.7. I would love to find an F50/1.4 but haven't seen one for sale in years.
