Pentax-F 50mm f1.7 lens.
Quite by accident, I was guided to the Oxfam online charity shop earlier today. Among other things Pentax, they have a Pentax P30T with a 50mm f1.7 lens for £75.00.
Of course there is no "rating" for their items, so you take pot luck. They also appear to ship items and have a returns policy. Maybe they even have a shop in your area/country? Just a heads up for everyone.
Kind regards to all, Rod.
