My Leica kit was an M2 and M4, plus one screw lens body. I think the screw body was a IIIc, though it may have been a IIIf. I don't remember for sure. I bought it from a great local camera repairman as a second camera along with a used M2. In late 1967 I added a brand new M4, which I loved with all my heart. The IIIc (or f) had a 50mm lens. Don't remember what aperture. The lens lineup for my M bodies was a Canon 35mm f/2, 50mm Summicron f/2, Canon 85mm f/1.8, and a Canon 135 -- I think it was an f/4. I took on several fun jobs with this gear. I spent a couple months of Saturdays shooting this dance class. I think this shot was the M4 with its Summicron.
I don't remember exactly, Rob, but it seems to me the M4 with Summicron was a little less than $600. Since our government has taken such care to insure our money doesn't lose value, $600 then would be equal to about $4,350 today. Nowadays the lens alone runs about $2,300, the 1967 equivalent of $320, and I can't make a comparison for the body, but the equivalent is out of sight.
But all is not lost. I have a 25mm Leica DG Summilix lens that I used on my Olympus E-P1, and now use on my Pen-F, a half-frame camera, making the lens the equivalent of 50mm. The Leica quality is there in that lens, and it goes for about $600. I have a range of lenses for my Nikons, but at heart I'm a 50mm guy, so the Pen gets a lot of use.
And, yes, as is usual with a Leica, the girl closest to us has her feet cut off.
