I got an FS1 with the 50 1.4 for £20 a couple of years ago, based on the thought "Hexanons are known to be pretty good, I could probably sell it on for more than £20"
I foolishly decided to put a "test roll" through it, and now it's accompanied by an FT1, 50 1.7, 40 1.8, a 28mm and a couple of 135mms.
I've been in what I've referred to as a "lazy autofocus slump" recently, but whenever I use the Konicas, I'm blown away by them.
