All right, I admit it was the cheapest one of all: a 135mm Hektor.

I find that the 135 Hektor doesn't have the contrasty 'snap' of the later Leica lenses, but it's plenty sharp. My 1954 version has wonderfully smooth bokeh, and at 5 feet can easily resolve the finest of hairs on my 13 year old son's face across the frame, even wide open (if you can call f:4.5 wide).
