I have a 1951 Leica 11f Rangefinder (screwmount) , with a Leitz Elmar, 50mm F 3.5 lens. I bought both camera and lens at the same time, in 1982 for I think it was around $330 CAD.
I wanted an M3, but couldn't afford one.
I've used my old 11f and Elmar 50 for over 40 years. Never a problem.
Takes photos that will compare well, with any modern camera. It has a dent on the top, the leatherette cover is wearing off. But the old Leica body, and even older Elmar lens (1940's I think)....just continue to work well. Manual focusing of course, but I do love the speed and accuracy of focusing, this camera.
I would say it is one of the best 300 or so bucks I've spent in my long life. As said before, I can't get over the image quality it produces, and the fact that I haven't had to repair it in the 40 + years I have had it.
So, that explains my 'attraction of my old Leica' , I think very well.
